Filippenko (UC Berkeley) report on\nbehalf of the KAIT GRB team:\n\nThe Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory responded to\nthe Swift trigger of GRB 090515 (Beardmore et al., GCN 9356) and began a\nsequence of filtered and unfiltered 20s images followed by a set of three 180s\nunfiltered images.  We detect no new source within the XRT error circle\n(Beardmore et al., GCN 9356).  Individual unfiltered 20s exposures starting at\n04:59:09 UT have 3-sigma limiting magnitudes (calibrated to USNO B1) of about\nmag 19.1.  Our combined set of 3x180s unfiltered images has an upper limit of\nabout mag 20.5 at a midpoint of 05:19:47 UT.",
