Hi Mike,
Thanks for your report. I was in the same situation - couldn't see
the
star due to moonlight illumination of thin clouds. I couldn't even
confirm it was the right field due to the paucity of
other stars. (My
GOTO is usually almost spot-on.)
The only other reports I've seen were Hazel McGee,
Bertrand Thooris, and
Tomas Janik, all negative. Hazel was just inside the southern track
limit.
Bertrand was half a track width south of the track in Belgium.
And Tomas was on the northern 2sd limit in the Czech
Republic. So I
don't know where the track went. But it's only by having a wide network
of observers that we can help to resolve track
positions. So please
don't give up on the programme :-)
Best regards,
Andrew

Andrew also commented; I was also rewarded with a brilliant
passage of the ISS chasing the ATV
Jules Verne 10 minutes later.

8.ADDITIONAL COMMENTS:
Conditions were perfect (apart from the street lights 20 m away,
so I used a sodium-D
filter). The two nearby stars of similar
brightness remained visible
throughout. I've given rather wide
error bounds because both the
disappearance and the reappearance
somewhat took me by
surprise. The duration appears to be much
less than expected, so it looks
like the path shifted by nearly
half a path width.
