(1) TWO MORE LUNAR IMPACTS CONFIRMED
From David Dunham <dunham@erols.com>
Pedro Valdes Sada reports two lunar flashes that he videorecorded
near
Monterey, Mexico, about half an hour after the event seen by
Brian
Cudnik and recorded by me that is now so famous. He gives
the times in
his message, copied below. They are also on my tape, made
in Mount
Airy, Maryland, at the times he gives! Later today, we will
digitize
these two new flashes and put them up at http://iota.jhuapl.edu
They are also near the lunar equator. We will be determining the
exact
times from the tapes when we can; I'm sure they will agree to
within
the 1/15th or so second of timing that we can probably recover
from the
tapes. I had a WWV minute tone recorded at 5:07:00 UT, 7
and 8 minutes
before the flashes, respectively. The new objects are also
probably
Leonids, since it was still near the time the peak was striking
the
Moon, but of course we do not know for sure, since we don't know
from
which direction the meteoroids approached the Moon.
For observers, a key to my success in this endeavor was the focal
reducing lens that I purchased from Orion; it decreased the
f-ratio of
my 5-inch Schmidt-Cassegrain telescope from 10 to 6.3. That not
only
increases the field of view by more than a factor of 3 in area,
but
also increased sensitivity by concentrating the seeing disk of
point
sources onto fewer pixels, and allowed, for example, recording
(faintly) the Earthlit dark side of the Moon.
By measuring images showing the lunar cusps and terminator taken
before
and after the 4:46:15 UT event, I was able to determine that it
occurred at an angle (measured from the Moon's center, called
"cusp
angle" in occultation terminology) of 77 deg. from the north
cusp.
Using also the distance of 1.7' in from the edge, this puts the
impact point in Oceanus Procellarum (Ocean of Storms) about 50 km
east-northeast of the center of the 50-km crater Cardanus, at
selenographic longitude 71 deg. W., latitude 14 deg. N., with
estimated
accuracy of 2 deg. or 50 km.

Subject: Re: Lunar impact seen & videorecorded; more records
sought
Hi David,
I videotaped the non-illuminated side of the
Moon for a while
before the leonid meteor radiant rose. There was some trouble
while
doing it because I had allready committed myself to help with a
large
number of people that attended a talk I gave that night on the
subject
and then stayed for the meteor shower. So I had to keep an eye on
the
camera and telescope at the same time I was answering questions
and
talking with people.
I checked my tape for the 4:46:15 UTC meteor
crash on the Moon and
could not find it. I must have been aiming elsewhere. I am not
sure
where because the FOV was too bright from the glare and I could
not see
the limb. Another problem was that the portable telescope was not
polar
alligned very well and I had to keep adjusting it every 5-10
minutes so
the Moon would not drift out of the FOV.
At any rate, I have not checked all the tape,
but managed to
identify two very suspicious-looking flashes that lasted at most
2-3
frames. They occurred at 5:14:13 and 5:15:20 UTC (+-1 second).
Please
check your tape and pass it along to see if anyone else can
confirm
them. The second one in particular, was right on the edge of my
camera's FOV. The first one I am pretty sure was real since the
image
was a bit out of focus and looked very much like the stars I
taped for
calibration after the Moon set (the focus must have drifted since
it
was OK at the start of the night). I will try and digitize the
two
frames involved. Unfortunately, on my VCR I can only freeze-frame
the
second fainter one. There seems to be a brighter one in between
frames
that I cannot freeze on the screen but can see momentarily. As
for
location on the Moon of the possible impacts I cannot say for
sure
since the Moon drifted constantly. I can say that it was near the
equator and close to the terminator since it drifted into the FOV
after a couple of minutes.
Sorry that I cannot be more precise on the location
and magnitudes.
I will try to grab the images involved and at least get a rough
estimate of the magnitude.
Regards,
Pedro Valdes Sada

(2) HALE-BOPP MAY HAVE A SATELLITE
From Explorezone, 23 November 1999
http://explorezone.com/archives/99_11/23_hale_bopp.htm
By Robert Roy Britt, explorezone.com
The suggestion that comet Hale-Bopp might have a satellite
orbiting its
nucleus, based on Hubble Space Telescope images, has resurfaced
amid
doubts.
Reporting in the current issue of Earth, Moon, and Planets, an
international journal, Zdenek Sekanina of the Jet Propulsion
Laboratory
writes about a Hale-Bopp satellite detected by applying
theoretical
modeling to images taken with Hubble's Wide Field Planetary
Camera 2 on
five days during 1996.
If further research confirms the satellite, it would be the first
known
cometary satellite discovered in a stable orbit, Sekanina said in
a
telephone interview.
While other satellites have been spotted around other comets,
they are
in each case drifting away from their host and destined to
eventually
break free from the relatively minor gravitational tug. Hale-Bopp
--
which made its closest approach to the sun in 1997 -- is a huge
comet,
and Sekanina said it is therefore a prime candidate for being
capable
of binding a satellite into a stable orbit. The satellite might
have
broken off the main nucleus during a previous pass through the
solar
system, he said, possibly because of the gravitational effects
of Jupiter.
Sekanina says the satellite is roughly 30 kilometers in diameter
(18
miles), compared with a main nucleus estimated to be 70
kilometers
across (43 miles). The two objects appear to be separated by
about 160
to 210 kilometers. The satellite appears to take two or three
days to
complete an orbit, Sekanina said.
Skepticism
Harold Weaver, a research scientist in the Department of Physics
and
Astronomy at the Johns Hopkins University, has doubts about the
report,
which is based on Hubble Space Telescope (HST) images Weaver has
studied (and actually provided to Sekanina). In a separate paper
due to
appear in an upcoming issue of Earth, Moon, and Planets, Weaver
and a
colleague, Philippe Lamy, make their case against the possible
satellite.
"We argue that Sekanina's conclusions about multiple nuclei
cannot be
trusted because he is trying to extract more information from the
HST
images than they contain," Weaver told explorezone.com.
"In particular,
the (detectors) on HST are not perfect devices, and one has to be
very
careful about interpreting every 'bump and wiggle' in the data as
evidence for companion nuclei. In other words, we feel that
Sekanina
may be overinterpreting the data."
Sekanina agrees with Weaver that the satellite (or second
nucleus) does
not appear on the Hubble images. "I don't see it
either," Sekanina
said. But while Weaver is an observer, Sekanina is a theorist. He
starts with the assumption that there is a satellite, then he
tries to
find it in the data using a complicated modeling process that
filters
the light reflected by dust surrounding the comet.
"The only way to extract the nuclei (from the images) is to
do a
digital modeling of the central cloud," Sekanina said. He
applied two
different techniques to five separate images. "I'm
reasonably certain
that something is there," Sekanina said, "because I see
it on each of
the five images using two different models of extraction of the
dust
cloud."
Weaver is familiar with the modeling method, and respects
Sekanina's
work in general, but still he doubts that there is anything
unusual in
the images. He noted that the new paper is similar to previous
papers
by Sekanina that used similar methods to reach a similar
conclusion.
"There are some interesting new results in the (new) paper
… but, in my
opinion, they do not strengthen the case for multiple
nuclei," Weaver
said. "Of course, we could be wrong."
Another group of researchers, writing in the September issue of
Astronomy & Astrophysics, claims evidence from ground-based
observations that indicates a second nucleus in Hale-Bopp. This
apparent second nucleus is a different one than that proposed by
Sekanina. It was derived by applying a technique called adaptive
optics, which attempts to filter effects of Earth's atmosphere
and
resolve objects that otherwise are not apparent in an image.
Weaver and Lamy also dispute this detection, based on Hubble
images
taken at nearly the same time but which do not show companions of
the
type claimed by the authors, "even though they should have
been easily
detected in the Hubble Space Telescope data."
Why does it matter?
Weaver said there are more than two dozen confirmed examples of
comets
splitting into fragments, the most famous recent example being
Comet
Shoemaker-Levy 9, which plowed into Jupiter in several stages. It
is
therefore conceivable that relatively large fragments could have
broken
away from Comet Hale-Bopp.
"However, no one has ever detected a bound companion to a
cometary
nucleus, as Sekanina is claiming, so that would be very
exciting,"
Weaver said. "There are now several known examples of binary
asteroids,
and maybe comets sometimes also have stable companions."
If a comet had two nuclei, Weaver said there is a chance the two
could
collide, "which would temporarily produce a large outburst
in activity
by the comet."
Meanwhile, Sekanina plans to get to work figuring out the orbital
details of his suspected satellite. One result of that effort
could be
a better understanding of comets in general. "If we can
calculate the
orbit, we could calculate the first mass of a comet ever,"
he said. ez

From NASA Science News <expressnews@sslab.msfc.nasa.gov>
NASA Space Science News for November 23, 1999
Last week Thursday's Classroom invited students, parents, and
educators
to watch the Leonid meteor shower and to submit their
observations
for use in a future episode. We've been deluged with
hundreds of
reports. Congratulations to all the new meteor scientists out
there!
Because of the large volume of data we're recieved, we won't post
these
observations until the December 9th episode on the upcoming
Geminid
meteor shower.
Meanwhile, this week's episode -- "Leonids Rain in
Spain" -- offers
some new meteoritic lesson plans based on the recent meteor
storm. If
you missed the sky show on November 18, you can recreate the
event in
your classroom with "A Questionable Meteor
Shower." Other activities
include "Time Travel Postcards," "Interview with a
meteorite," and
"Diamante Meteor Poems."

(5) DEAD SEA SUB DIVES FOR LOST CITY OF SODOM
From Fox News, 22 November 1999
http://www.foxnews.com/js_index.sml?content=/scitech/112299/times_sodom.sml
By Jonathan Leake , The Sunday Times
Sodom, the biblical world's most sinful city, is about to get its
first
visitor since Lot left in haste as it was destroyed by heavenly
fire
4,000 years ago.
A British researcher will this week venture to the bottom of the
Dead
Sea — where Sodom's remains are thought to lie — in a
mini-submarine.
Michael Sanders, a Leeds-born biblical scholar, has found what
appears
to be the remains of the city under the surface of the Dead Sea
by
studying satellite pictures taken by the National Aeronautics and
Space
Administration (NASA). His findings have been backed by the Dead
Sea
research unit from Tel Aviv University, whose scholars are on
site with
him.
"We are about to embark on our first dive. Finding the
biblical city of
Sodom would be the greatest achievement of my life," he said
last week.
The dives come just as the British Museum prepares to announce
the
results of its research in the area, which appears to confirm
that
Sodom was located there. A team excavating a Byzantine church has
found
what is thought to be the legendary Cave of Lot hidden behind it.
According to the Bible, Lot and his daughters took refuge in a
cave
while Sodom lay smouldering. It was there, thinking they were the
last
people on Earth, that they decided to start a new generation.
To most people, including archaeologists, the biblical story of
Lot,
Sodom and Gomorrah is metaphorical, a warning to sinful humans
from the
authors of Genesis. No satisfactory archeological evidence of the
five
lost cities of the plain, of which Sodom and Gomorrah were two,
has
ever been unearthed.
Other scholars, however, including Sanders, believe Sodom and
Gomorrah
not only existed but that they were also probably destroyed in a
catastrophe about 5,000 years ago and that their ruins were
engulfed
beneath the salty waters of the Dead Sea.
Sanders's findings are supported by Dr. John Whitaker, a
geologist at
the University of Leicester, who has found strong evidence of a
powerful earthquake in the area at that time.
He said in a research paper: "Their remains have not been
found because
they are now under water. The total disappearance of the Vale of
Siddim
and its cities beneath the lake would explain the lack of
archeological
evidence. Further underwater exploration could be
revealing."
Sanders believes the remains of the ancient cities are to be
found off
the northwest shore of the Dead Sea, about 10 miles south of
Jericho.
The orange Delta mini-submarine, on hire at a cost of almost
£5,000
($8,000) a day, was the one used to explore the wreck of the
Lusitania.
The 10ft-long, 6ft-high vessel was flown into Israel from
California
last weekend. It holds two people and can stay submerged under
hundreds
of feet of water for up to three days, but the team will be
making only
short dives.
Sanders watched on Friday as the vessel was winched aboard a
barge at
the Ein Gedi oasis in preparation for its journey to the northern
shore.
The Dead Sea may be only about 200 meters deep, but Sanders is
diving
into murky diplomatic waters. The northwest corner of the sea is
in the
West Bank, which was ruled by Jordan until the six-day war in
1967 and
has been under Israeli military occupation ever since. Now the
Palestinians have claimed it for their nascent independent state.
The
expedition therefore had to be cleared with the Israeli army, the
Jordanians and the Palestinians — and if Sanders does find
anything
down there, there will be a diplomatic battle over ownership.
Not everyone is as convinced as Sanders, however. Dr. David Neev,
a
respected Israeli geologist, has dedicated much of his life to
the
scientific study of the Dead Sea and its surroundings. He rejects
Sanders's thesis that Sodom and Gomorrah are lying at the bottom
of the
northern end of the Dead Sea.
"The Bible is not always reliable in its chronology, but its
geographical descriptions have always turned out to be perfect.
According to the Bible the towns of Sodom and Gomorrah were
located at
the south end of the Dead Sea, next to Mount Sedom and a long way
from
Sanders's site," said Neev.

OBJECTIVES: to provide a deeper knowledge to researchers working
in the
different fields of dynamics and even of plasma physics on topics
which
have undergone parallel and certainly complementary developments,
among
communities which have a few occasions to meet, essentially
mathematicians of dynamical systems and physicists in dynamical
fields,
familiar with numerical tools.
MOTIVATIONS: The theory of chaos plays a major role in various
domains,
not only in modern physics (e.g., celestial mechanics, fluid
mechanics,
solid state physics, ...) but also in other branches of knowledge
such
as biology and economics. Major results have been obtained
specially in
astronomy and gravitational systems.
A first kind of chaos due to the interaction between different
types of
resonances (mean motion and secular), refered as "weak
chaos", has been
detected in the motion of terrestrial planets of our Solar System
by
Jacques Laskar; theoricists in the 60s had already discovered
this kind
of chaos and the presence of invariant tori in hamiltonian system
with
small perturbations (KAM theorem).
Another source of chaos exists and does not involve the
interaction
between resonances. However, it is also responsible for the fast
transport as well as for the diffusion outside the Solar System
of
small bodies such as comets and potentially dangerous asteroids
(Near-Earth asteroids). The sources of this kind of chaos are
planetary
close approaches, and this is the main topic of the school.
The objectives and organization of the school are thus:
- To provide a clear introduction to mathematical methods as well
as a
state of the art on the theory of singularities in gravitational
systems. One third of the school will be devoted to this aspect.
Lectures will be presented by mathematicians and physicists who
are
used to numerical tools.
The second part of the school will be devoted to the
modelisation
and to the construction of mappings in which delta functions are
used
to simulate close approaches as "shocks".
The third part will present the state of the art on the
diffusion of
comets, asteroids, meteroids and planetary rings. The application
of
the knowledge on close approaches (singularities) to the
determination
of spacecraft's trajectories, like Cassini, will also be
presented.
Since, the gravitational forces are not the only forces
which have a
denominator proportional to the square of the distance, the
community
working on plasma physics may also be interested in this school.
- Between the proposed lectures, a certain number of short
communications on the topic will be presented mainly by young
researchers.
------------------------------------------------------------------------
COST AND PAYMENT PROCEDURE
As usual, the "Formation Permanente" will take care of
the cost of the
Hotel room and the registration fees of CNRS researchers. Travel
expenses will be paid only for CNRS researchers belonging to the
Regional Delegation 20 (Sophia-Antipolis). Other CNRS researchers
must
ask the refund of their travel expenses to the "formation
permanente"
of their own Delegation.
Then, if our finances allow it, we will also totally (or at least
partially) take care of the Hotel room expenses of our french
colleagues of the "Enseignement Superieure" as well as
those of some
french PHD students. They may then ask to their own laboratories
for
the refund of their travel expenses.
NB: A possible partial or total refund by the School will be
effective
only if the persons stay for the integrality of the School.
We give below the necessary information concerning the payment
procedure
corresponding to the different situations.
1- CNRS researchers must send a cheque of guarantee for 500
French
Francs (order: ADION) at the address given below. It will be
given back
to them at the School. The formation takes care of the
registration
fees.
2- French citizens non CNRS researchers must send a cheque of
guarantee
for 500 French Francs (order: ADION) at the address given below.
It
will be given back to them at the School in exchange for
registration
payments of 300 French Francs.
3- Non French citizens must send a cheque of guarantee of 500
French
Francs (order: ADION) at the address given below, possibly
converted
in their own currency or better in Euro or US $. It will be given
back
to them at the School in exchange for registration payments of
300
French Francs. The Hotel room cannot be paid by the Formation.
The
price is 2430 French Francs per person (full board for 6 nights)
on the
basis of a double room, and 3060 French Francs for a single room
(limited number). Hotel rooms will have to be paid during the
School,
directly at the Hotel, in cash or by credit card.
4- For accompanying persons who do not follow the School, only
the payment
of the room will be required (no registration fees).
IMPORTANT: given the low rate with respect to the location and
standing
of the Hotel, NO MONEY SUPPORT can be provided to attend
the School.
DEADLINE: DECEMBER 1, 1999. Late people will take the risk that
no
place is left. The cheque of guarantee to ADION as well as the
registration form given below (to be sent also by Email as to
