Report from Arto Oksanen
The weather got worse and worse, but I could observe a bit over three hours
(Jan 19/20, 2003 23:23-03:00 UT). The light curve is very interesting, lots
of 9-10 minute 0.1 mag oscillations and larger 'flares', one lasted 20
minutes. There was a fading trend but it turned to slow rise after 2 UT.
There seem to be very short timescale flickering as light curve looks noisy
even though S/N was over 200 in the beginning of run.
