TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2095 SUBJECT: SDSS 0.5m PT observations of GRB030329 DATE: 03/04/05 01:02:21 GMT FROM: Brian Lee at LBL <bclee@lbl.gov> B. C. Lee, D. Q. Lamb, D. L. Tucker and S. Kent on behalf of the SDSS GRB team, report: The optical transient associated with GRB 030329 (Peterson and Price, GCN 1985; K. Torii, GCN 1986) was observed with the SDSS 0.5m "Photometric Telescope" (PT) at two epochs, starting March 31.181 UT and April 01.153 UT. The preliminary r-band magnitude at March 31.181 UT was observed to be 16.60 +/- 0.02, and the u g r i z data on that date is well fit by a flux power law of approximately nu^-0.94, or nu^-1.0 if a reddening of E(B-V)=0.025 is applied (Bloom, GCN 2011 and Schlegel et al. 1998). The April 01 UT images are still being processed. Our ugriz photmetric catalog of other objects in the field will be made available upon request; please email bclee@lbl.gov or visit the follwing web page: http://supernova.lbl.gov/~bclee/grb/ This message may be cited.
