TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2112 SUBJECT: GRB030329: BV photographic observations DATE: 03/04/07 15:09:40 GMT FROM: Vasilij Rumjantsev at CrAO V.Metlov (Crimean Laboratory of the Sternberg Astronomical Institute, Moscow State University) report: I have continued photographic observations of the GRB030329 OT found by B.A.Petrrson and P.A.Price (GCN 1985) with 50-cn Maksutov telescope at Crimean Laboratory of the Sternberg Astronomical Institute. Two 80-minute exposures have been made on Apr, 4. Based on additional filed photometry presented in GCN 2082 by A.Henden I have estimated the OT magnitudes on two new photographs, and also have made some corrections to my previous (GCN 2102) estimations. 14 stars were used to do the calibration. The results are shown in the table below. The increased uncertainties of last measurements are caused by affinity to the limiting magnitudes of our plates (19.0-19.5 in B band, 18.0-18.5 in V band). Despite of it, it was seen, that began a new fading phase. date UT filter mag err 2003-04-02 19:33:00-20:33:00 B 18.20 0.15 2003-04-02 20:45:00-21:35:00 V 18.05 0.25 2003-04-04 18:18:00-19:38:00 V >18.4 - 2003-04-04 19:48:00-21:08:00 B 18.80 0.30 This message may be cited.
