A. C. Updike and D. H. Hartmann (Clemson University) report on behalf of
the Clemson GRB Follow-Up Team:
The .9m SARA telescope began imaging the field of GRB 061028 4 hours and
51 minutes after the Swift Trigger 235715 at 01:26:22 UT. Our initial
observations were comprised of 180-second exposures in the I band.
After stacking in sets of 5, we did not detect any new sources. Our
observations continued with 300-second exposures in the I band, 6 hours
and 6 minutes after the trigger. Based on a total of 25 minutes of
stacked I-band exposures we conclude that the XRT error circle (GCN
5762) does not contain a new or fading source to a limiting magnitude of
I ~ 20.1 � .4 mag (based on calibration of 10 field sources from USNO
B1.0 I2 band).
