GCN Circular 2012
P. Martini (OCIW), P. Berlind, K. Z. Stanek (CfA) and P. Garnavich (Notre Dame): We imaged the optical afterglow of GRB 030329 (Peterson & Price: GCN 1985; Torii: GCN 1986) with the Magellan 6.5-m Clay telescope and LDSS2 imaging/spectrograph on March 30 UT 01:15 (13.6 hours after the burst). We also obtained imaging data with the FLWO 1.2-m telescope. The R-band magnitude is estimated to be 15.1 assuming star "A" is R=16.2 (see http://cfa-www.harvard.edu/~kstanek/grb030329.ps). Thus the OT continues to be very bright. We should note that the several fairly bright objects closest to the OT are clearly resolved in our images and should not be used for relative photometry. "A" and "B" appear to be stellar at ~1.3'' seeing. The foreground reddening from Schlegel et al. (1998) is E(B-V)=0.025. This message may be cited.
