W. Li and A. V. Filippenko, University of California
at Berkeley, on behalf of the KAIT GRB team, report:
The robotic 0.8-m KAIT located at Lick Observatory responded to
GRB 111029A (Swift trigger 506519; Troja et al. GCN 12498) automatically
and started the first image at 09:47:15 UT (154.5 seconds after the burst).
A series of images were taken in the V, I, and clear filters.
No new sources were detected within the Swift/XRT error circle
in the KAIT images (single or stacked frames) when compared to
the DSS II. We set the following specific limits (calibrated
to USNO B1):
start UT end UT t_exp(s) mlim (unfilt.) coadd?
