GCN Circular 5844
S. B. Cenko (Caltech) reports on behalf of a larger collaboration: We have imaged the field of GRB 061121 (Page et al., GCN 5823) with the automated Palomar 60-inch telescope. Observations consisted of 25 x 180 s exposures in the Kron R and Sloan i' filters, taken at a mean epoch of approximately 11:30 22 November UT (~ 20.1 hr after the burst). The afterglow is clearly detected in our images, and we measure the following magnitudes (calculated with reference to the USNO-B catalog): R = 21.0 +/- 0.25 I = 20.3 +/- 0.21 The large errors are dominated by photometric uncertainty. We note the R-band measurements are consistent with nearly-simultaneous observations reported by Halpern et al. (GCN 5840). Further observations are planned.
