Hi all,
a cold front
reached us at eclipse start, but some minutes after
maximum eclipse we had quite good conditions. See pictures at

[SEML] Re: Partial Lunar Eclipse
I tried to acquire total eclipse
like reddening of the umbra. With
really long (1-4-second) exposures
and after some photoshop, the
Moon in umbra is visible. Generally neutral color, maybe bluish to
the edges and faint reds deeper.
It was sometimes visible during the eclipse, but I do not think it
would be an exceptionally bright eclipse, had it been total.
Good day,

Russia, Novosibirsk. The partial lunar eclipse on 7 September
2006.
Even several days before the eclipse Novosibirsk found itself
in huge
anticyclone, that provided a long period of virtually
cloudless weather. In
local time the first penumbral phase was to begin just ahead
of midnight
(23:42:19 l.t.), so I didn't came to bed before the eclipse.
Visibility of
this eclipse was very favorable for Novosibirsk. The Moon
culminated on very
comfortable altitude of 27°
not long before the moment of maximum, this gave a
very good sight during all the eclipse. I periodically make
shots with my
digital photo camera, the first signs of darkening appeared
on the Moon disk
nearly a half on hour after the penumbral phase began. Closer
to the first
partial phase moonlight in my backyard had significantly
weakened, with
notable improvement in stars visibility. Finally the Moon
began entering in
the Earth's umbra. It should be noted, that taking shots of
partial phase of a
lunar eclipse I was less successful than before because of
great difference
in brightness of various parts of the lunar disk. Looking at
the Moon through
binoculars when it was maximum phase and its north-western
limb was in the
umbra, I saw this darkened piece of the Moon very good and it
seemed to me
that it had some reddish colour. Perhaps, the Earth umbra
this time was quite
"light". The illumination level in my backyard was appr.
corresponding to the
not eclipsed Moon in phase ~0.2-0.3, I could see the stars
nearly 1 mag fainter
then before the eclipse. After the maximum events went in
backward direction.
Umbra, and later penumbra, was gradually moving to the
western limb of the
Moon, the sky and ground again began gelling more lit and a
half an hour
before the end of last penumbral phase everything became as
usual during the
full Moon - the sky and backyard lit with bright moonlight.
The next eclipse
in Novosibirsk will be the full lunar eclipse on 4 March
2007.
It will be visibly almost completely except of the last
penumbral phase.

A cold front was meeting the eclipse at moonrise so we missed the first
part, the moon rose over the clouds some minutes after max. eclipse,
with its red-brown colored eclipsed part first. Good viewing conditions
for the remaining eclipse time.

Timings for Partial Lunar
Eclipse 2006 September 7.doc
Hi Byron
Herewith my timings. Weather
not great, but there should be some useful times.
It was not always easy to decide the
moment of contacts as to be expected so close to the edge of the shadow with an
eclipse of small magnitude, so I am very interested as to what you determine.

Oblateness of the umbra in Lunar
Eclipses
Good morning,
I have studied 51 lunar eclipses to the present time and have determined an improved value for the oblateness of the Earth's atmosphere of 1/102.
My present work can be seen at
http://www.netspeed.com.au/minnah/finder.html
I will also be presenting this data to Fred Espenak at NASA
in the near future.

Dear Fred Espenak,
I have a detailed proposal for your consideration concerning
the prediction of times of lunar eclipses.

I've been doing some more work with my code, to identify the
cause for the
times being some 30 secs late. Fixed that up. Then looking at
the predictions
on Fred Espenak's page, it is clear to me that he has not
allowed for any
oblateness in his predictions. He has merely used the
expressions in the old
explanatory supplement, using a constant earth radius as at
45 deg latitude.
Fred's predictions are:
Penumbral Eclipse Begins: 16:42:23 UT
Partial Eclipse Begins: 18:05:03 UT
Greatest Eclipse:
18:51:21 UT
Partial Eclipse Ends:
19:37:41 UT
Penumbral Eclipse Ends: 21:00:20 UT
You will note that the times of my third prediction are
different from his by
a constant 1 or 2 secs - which is almost certainly due to a
different deltaT
correction. [I'm fairly sure of this - his solar eclipse
predictions indicate
how he apples this, and he doesn't understand the
relationship of deltaT with
UTC. Also if you were to disregard the leap second introduced
at the start of
this year, my times would be 1 second later....] I
think when he says he has
included oblateness effects, all he has done is reduce the
radius to that at
45deg.

Subject: Lunar Eclipse this Friday morning
This particular eclipse is of particular interest to Byron
Soulsby, as the
moon enters the umbra at close to the north pole.
The particular interest is that from his analysis of lunar
eclipses over many
decades, Byron has deduced the Earth's atmosphere has a
greater oblateness
than the Earth itself. Whereas the Earth is 1/298, Byron
believes the eclipse
data shows the value that should be used to represent the
atmosphere for lunar
eclipse predictions is about 1/102.
To illustrate the impact of this, the following are two sets
of predictions
for this eclipse. The first is based on Byron's value of
1/102. The 2nd is
based on the Earth value of 1/298.
Oblateness = 1/102

As you can see, the contact time for the moon entering the
umbra differs by 90
secs odd. And because this eclipse has the contact location
at the pole, the
time difference caused by the value used for oblateness is
maximised - see the
much smaller difference for the Moon leaving the umbra.
Recognising that contact times are not easy to accurately
measure, I think
Byron would like to hear from anyone/everyone who can time
the contact time.

Attached are some predictions for Friday morning. In order
they are:
Fully corrected for oblateness, f = 1/102
Fully corrected for oblateness, f = 1/298
Uses a circular Earth, radius as at 45deg, f=1/298
The Umbra ingress is truly determinative....

Hello Byron,
I had a go at timings of the partial lunar eclipse of 2006
Sep 7. The sky was
quite clear (just as well the event wasn't on 24 hours
later!).
First umbral contact proved to be more difficult than I
expected, because it
was hard to be confident the umbra was actually on the Moon
until a few
minutes later when a significant portion of it was obvious.
However, going
back over my commentary on the tape,
I can say this: by 18:06 UT (4:06 am
AEST) there was definitely no hint of any darkening
on the lunar limb (other
I also tried a few crater timings before the Moon went behind
the trees. I had
the usual problem of deciding where exactly the edge of the
umbra was,
exacerbated by the varied albedoes of the mare/highland
terrain which caused
the shadow edge to have different contrasts according to the
terrain. So my
timings have an uncertainty of about plus or minus 2 minutes,
but here they
are for what they're worth:
~18:13 UT LA CONDAMINE A
~18:21:30 PLATO (midpoint)
~18:25:30 PICO
~18:39:30 CASSINI A
~18:43:30 CALIPPUS
Some of these times are ahead of the predictions, so I may
have been picking
the leading edge of the shadow instead of the "mid-shoulder",
but as I said, I
didn't find it easy.

Subject: Closest Full Moon of 2006
Space Weather News for Sept. 7, 2006
http://spaceweather.com
BIG FULL MOON: Tonight's full moon is the closest and
biggest of 2006. Why?
The Moon's orbit is lopsided: one side is closer to Earth
than the other. When
the Moon turns full on Sept 7th, it will be on the close
side, making it seem
a bit wider than usual. Look for the extra-wide Moon rising
in the east at
sunset--very pretty.
BONUS--A LUNAR ECLIPSE: If you live in eastern Europe,
Asia, Africa or
Australia, you might also see a partial lunar eclipse
tonight. The Moon will
dip into Earth's shadow for about 90 minutes around 1851 UT
on Sept. 7th. Only
19% of the Moon will be covered, but that's enough for a nice
display. Maps
and animations may be found at
http://Spaceweather.com .
A SPOT OF FOLKLORE: September's full Moon is usually called
the Harvest Moon,
but not this year. By definition, the Harvest Moon is the
full Moon closest to
the autumnal equinox. This year's equinox falls on
Sept. 23rd and the full
Moon closest to that comes on October 7th. The 2006
Harvest Moon will have to
wait until October.
