[Aavso-photometry] Time series for GK Persei

[gianlucaros at gmail.com]

I have experimented to take TS of GK Persei on Feb 24th to see if I
can detect the small fluctuations around minimum. I have actually
taken 5 consecutive exposures 20 sec each and done the calibration
with both darks and flats. Since I get 5 different mag value (13.19,
13.23, 13.13.27,13.22,13.23) I wonder whether such measurements are
indication of the behaviour of the star rather than problems in
accuracy. Sorry for asking a question that could be trivial to answer.
