Bloom (UCB) report:\n\nWe acquired imaging of the field of short-hard burst GRB 100216A \n(Cummings et al., GCN 10428) on 2010-02-19 starting at 07:31 UT, using \nLRIS on Keck 1.  A total of 660 seconds of imaging was acquired in \nR-band and 900 seconds in g-band simultaneously.  The imaging covers \napproximately 90% of the BAT error circle including the nearby galaxy \nmentioned in GCN 10428, a barred spiral at z=0.0378.  In a preliminary \nreduction of the R-band frames we identify no new source within the \nfield, down to the SDSS limit of approximately R>22 mag.",
