GCN Circular 1536
I. Burud, A. Fruchter, J. Rhoads, and A. Levan (STScI) report for the larger GOSH (GRB Optical Studies with HST) collaboration: We observed the field of GRB 020322 with STIS in open (50CCD) mode on UT 2002 April 8 and on June 5. The position of the transient with respect to the STIS image was determined by performing relative astrometry using the optical image of the transient from Bloom et al. (GCN 1296). The accuracy of the position translated to the HST image is estimated to be 0.08 arcsec. We see no evident OT, but at the position of the transient there is an extended 27th magnitude galaxy which is likely to be the host. The sum of the two epochs of observations is displayed at http://www.stsci.edu/~fruchter/GRB/020322 When subtracting the images from the two epochs no residual signal is detected above 3 sigma near the position of the OT, giving a limiting magnitude of 30.1 mags for any transient. Based on the ground-based observations from Bloom et al. (GCN 1294), Greiner et al. (GCN 1298), Hjorth et al. (GCN 1300) and Williams et al. (GCN 1307) and the non-detection of the OT in the HST/STIS image we conclude that the late time R-band decay of the OT must be steeper than 2.0. A plot of all the data points can be found on the aforementioned web page. We thank J. Bloom and the Caltech GRB group for making their ground-based data rapidly public (GCN1296).
