"As the satellites orbiting at those altitudes suddenly encounter
thicker air, they slow down."
No, they don't, they speed up.
Clearly, the writer has no knowledge of orbital dynamics.

"then based on correlations dating back to 1804 when the astronomer Royal, William Herschel, one of the greatest astronomers of all time".
Herschel never was Astronomer Royal.
In 1804, Maskelyne was the holder of that post.

None of the reports that I've seen quote the closing velocity
of the impact, which was 10 km/second (6.2 miles/second).
More bang for your bucks (and roubles).

Right first time Magic and Calum.
...and here they are:

How about TWO opportunities to view this eclipse, and guaranteed to
be free of cloud?
At about 10.13 and again at about 11.30 U.T. about 50% of the solar
disc will be covered as seen from the International Space Station.
If they do not manoeuvre the station upwards on July 23, as is scheduled,
then the crew would get to see a 90% eclipse.

======================
My winter forecast will follow in the next couple of months , im just gathering some data , which may take a while
nigel
I think you need to check the dates of New and Full Moons in
January and February 2009.

...and what calendar is being used now?

" are those black things stocks? "
No, those are pillories.

She said her name was stella, inter stella
Did somebody call my name?

You won't see any of those, Russell since the location is not
specified and they are therefore calculated for a point in
the gulf of Guinea at lat=0°, long=0°.
You must set your latitude and longitude (50°.6846N, 1°.5092W),
and your preferred time zone in order to get predictions for
your own observing site.

Two too keep a sharp eye on
May 6th NEW MOON at 0355 half hour earlier moon will be PERIGEE at 0323 {same day]
May 20th FULL MOON at 0211 APOGEE same day at 1429hrs
Ime going for strong winds around the 6th may , also there should be some decent wave heights , { i know you like taking pics of waves] lol should be interesting
On the 6th moon will be orbiting the earth at around 357771{distance] from earth
NIGEL
New Moon is on May 5 at 1218 UT I think.

Lapsus calami. Mutatis mutandis:
Neither. Independent sources quote 133 nautical, 153 statute miles.
Which observational method did you use, laser rangefinder, Doppler RADAR, orbital period and triangulation, telemetry interception from the SM-3 or some other method?
ffO
I used simple binoculars and stopwatch, to obtain the orbit from
positions relative to the background stars.
-
My observations indicate that it was orbiting at a height
of 133 nautical miles. The Pentagon states "153 nautical miles".
Who do you want to believe?
-
The middle of the eclipse is also the time that the U.S. SM-3 missile is
due to impact the errant secret USA 193 satellite.

Just hype. Everyone likes a good disaster story. That's why there are documentaries on it, because they draw in the viewers. The end of the world when it will come though will likely come up on us slowly and without us really knowing. It'll be very subtle.
The world ends not with a bang but with a whisper. H.G. Wells said that I think.
This is the way the world ends
This is the way the world ends
This is the way the world ends
Not with a bang but a whimper.

Couldn't you have been a little more polite Stella?
There is nothing 'ad hominem' about that response.

It's becoming an 'edge of yer eye' comet now though as it fades away. I hadn't known it did the same thing in 1898 though. They seem to reckon it's own internal gasses blow off a chunk (pancaked shaped?) every so often as it traverses around the sun. I have enjoyed it being up there though! What's next????
November 6 1892, actually.

Selsey?
Thats Patrick Moore home town, I wonder if he took it from Patrick's garden?
It looks like a pearl light bulb
That will be Pete Lawrence, probably Britain's best astrophotographer.

An impact that creates a hole 100 ft by 20 ft in dimension, would release
enough energy to be detected by seismometers around the world.
No such detections have been noted.
Any meteor seen in the sky around the time of the explosion, would
be coincidental.
I would speculate that this was more likely to have been the
ignition of a pocket of volatile gas, possibly by lightning.

Quicquid non nitet notandum?

"There are many things they might be, but no evidence whatsoever that they are 'spaceships' - indeed I would say that logically it's one of the least likely explanations."
I find that 98.8% of all the UFOs that I see do turn out to be spacecraft.
The last two - on August 2 were TSX5 (00-30A) at 22:51:39.28 U.T
and Cosmos 1386 rocket (82-69B) at 23:05:19.40 U.T.

"Do you only post on here to correct mistakes, because it feels like it."
No, I would post other events, but I find that I've been beaten to it by you!

I have the partial phase as beginning at 21h 30m U.T.

Close Encounter With A Asteroid
in Space, Science & nature
Posted
"On the night of March 1st (2nd UTC) we will have a small asteroid pass by us very close. At this point it looks like .00030 lunar distances."
One lunar distance is 384,000 km.
So .0003 lunar distances is (.0003x384,000) km
=115.2 km.
Earth's radius is 6378.2 km at equator.
So the asteroid is 6263 km beneath the surface.
