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
