![]() TITLE: GCN CIRCULAR NUMBER: 9715 SUBJECT: GRB 090726: Afterglow candidate photometryfrom Crni Vrh DATE: 09/07/27 15:43:32 GMT FROM: Jure Skvarc at OCV <jure@ing.iac.es> S. Maticic, and J. Skvarc on behalf of PIKA observing program at Crni Vrh Observatory. We present photometry of the source reported by Moskvitin, Fatkhullin
and Valeev (GCN 9709). The object was observed from Crni Vrh
Observatory with a 60 cm telescope using R filter and a CCD. First
exposure started at 2009-07-26 22:44:31 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. Comparison stars were 1629-0117020,
1628-0121875 and 1628-0121948 using R2 magnitudes from the USNO B1.0
catalogue.
