Dear colleagues,
my friend Tomas Hynek obtained on 10./11. Mar. 2002 an one hour long
unfiltered CCD observation of GK Per (total 40 images/points). The resulting
light curve seems to be interesting - in the first half of the run the star
varied quasiperiodically with amplitude ~ 0.1 mag, in the second half it
showed something like a maximum (~ 0.25 mag high). The sky was perfectly
clear, no clouds.
The dataset with detailed description and with an identification image was
sent to vsnet-campaign-data (# 92), the lightcurve preview can be seen at:
