D. A. Perley, C. R. Klein, A. N. Morgan, and W. Li (UC Berkeley) report
on behalf of the KAIT follow-up team:
The Katzman Automatic Imaging Telescope (KAIT) responded to GRB 100728A
and began taking data starting less than one minute after the trigger.
A moderately bright optical transient not present in DSS survey imaging
is visible in the initial set of exposures at the following position:
RA = 02:56:13.48
dec = +00:16:51.8
(J2000)
We measure I = 18.7 +/- 0.3 mag at 10:33:51 UT (t = 95 secs after the
BAT trigger)
In addition, we also manually slewed the 1.0 meter Nickel telescope and
began taking data starting at 6.6 minutes after the trigger; the
afterglow is also well-detected and is seen to fade in subsequent
exposures. Follow-up is continuing.
