TITLE: GCN CIRCULAR NUMBER: 5049 SUBJECT: GRB060502: Super-LOTIS Observations DATE: 06/05/02 07:13:21 GMT FROM: Grant Williams at Steward Observatory G. G. Williams (MMTO), and P. A. Milne (Steward Observatory) on behalf of the Super-LOTIS Collaboration, report: The robotic 0.6-m Super-LOTIS telescope began observing the error box of GRB060502 (Swift Trigger 208169, GCNC 5047) at 03:20:46 UT, 1034 seconds after the burst (17.23 min; 33 seconds after the delayed GCN notice). Our initial observations include 5 x 10s exposures, 5 x 20s exposures, and 30 x 60s exposures, all in the R-band. Under thin cirrus we do not detect the Swift afterglow reported by La Parola et al. and Cenko et al. (GCN 5047 & 5048) in our earliest 60 second exposure to the following 3-sigma limiting magnitude estimated using nearby USNO-B1.0 stars: t_mid obs (UT) exp t (s) t-t_0 (s) Limit -------------------------------------------------------- 03:24:56 60 1284 R > 17.9 Additional observations and analysis, including image stacking, are ongoing.
