D. A. Perley, M. Kislak, and M. Ganeshalingam (UC Berkeley) report:
We imaged the field of short GRB 090515 (Beardmore et al., GCN 9356)
with the Nickel 40-inch telescope at Lick Observatory starting at
04:52:57 UT (7.8 minutes after the trigger) in BVRI filters. No object
is detected within the XRT error circle (Osborne et al., GCN 9367) in
any exposure or in stacked frames. Approximate upper limits (relative
to SDSS):
tmid(min) exp(sec) filt lim(mag)
8.3 60 B > 19.9
10.0 60 V > 20.5
22.5 720 I > 20.3
38.1 600 R > 21.3
