Hi Alan

>From various photometric sources, the GRB afterglow was about mag 19.1 when
I took my picture (It had been as "bright" as mag 18.0 earlier in the
evening.

I wasn't even aware of it until about 1am when I was checking emails whilst
having a "cuppa" (that's a cup of hot tea) while the ccd camera was taking
dark frames.

I was lucky to get the picture, as earlier I apparently had ice crystals on
the window in front of the ccd camera (see this pic taken earlier of
NGC6946:  http://www.astropics.co.uk/6946noise.jpg  it was quite a damp
evening, which may have caused this or it might have been moisture on my
secondary mirror. Anyway, it was dissipating when I imaged the GRB
afterglow, thus the very uneven background to the picture.

It wasn't till the following morning I found out I was one of the few people
in the UK ever to have imaged this type of event.
