TITLE: GCN CIRCULAR NUMBER: 8569 SUBJECT: GRB081126: Afterglow photometry from Crni Vrh DATE: 08/11/28 00:08:26 GMT FROM: Herman Mikuz at OCV J. Skvarc and H. Mikuz on behalf of PIKA observing program at Crni Vrh Observatory. We confirm variability of the source identified by Sergeev and Pozanenko (GCN Circ. 8558). The object was observed from Crni Vrh Observatory with a 60 cm telescope using R filter and a CCD in about 5 arc-second seeing conditions. First 60 s exposure started at 2008-11-26 21:35:32 UT. All twenty exposures were of 60 s. The table contains the time since the Swift GRB detection to the middle of exposure in seconds, R magnitude and formal 1-sigma magnitude error estimate.
