Levan (STScI) report for the\nlarger GOSH (GRB Optical Studies with HST) collaboration:\n\nWe observed the field of GRB 020322 with STIS in open (50CCD) mode on\nUT 2002 April 8 and on June 5.  The position of the\ntransient with respect to the STIS image was determined by performing\nrelative astrometry using the optical image of the transient from\nBloom et al.  (GCN 1296).  The accuracy of the position translated\nto the HST image is estimated to be 0.08 arcsec.\n\nWe see no evident OT, but at the position of the transient there is\nan extended 27th magnitude galaxy which is likely to be the host.\nThe sum of the two epochs of observations is displayed at\n\nhttp://www.stsci.edu/~fruchter/GRB/020322\n\nWhen subtracting the images from the two epochs no residual signal is\ndetected above 3 sigma near the position of the OT, giving a limiting\nmagnitude of 30.1 mags for any transient.\n\nBased on the ground-based observations from Bloom et al. (GCN 1294),\nGreiner et al. (GCN 1298), Hjorth et al. (GCN 1300) and Williams et\nal. (GCN 1307) and the non-detection of the OT in the HST/STIS image\nwe conclude that the late time R-band decay of the OT must be steeper\nthan 2.0. A plot of all the data points can be found on the aforementioned\nweb page.\n\nWe thank J. Bloom and the Caltech GRB group for making their ground-based\ndata rapidly public (GCN1296).",
