[vsnet-outburst 7367] GK Per outburst: short-term variation

[Taichi Kato]

   Pavol Dubovsky and Nakajima-san reported Time-series CCD
photometry on Dec. 15-17.  The rising trend during these
intervals were not apparent.  On all nights, medium-amplitude
(up to 0.2 mag) variations were recorded.  Both hour-scale
and shorter period modulations were present.
More analysis will be presented later.
