TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5065 SUBJECT: GRB 060502B: AROMA optical observations DATE: 06/05/03 08:44:18 GMT FROM: Kazutaka Yamaoka at Aoyama Gakuin U I.Takahashi, T.Uehara, K.Yoshida, A.Kobayashi, K.Tanaka, Y.E.Nakagawa, S.Sugita, K.Yamaoka, A.Yoshida (AGU) report: The robot optical telescope, AROMA, at Aoyama Gakuin University (AGU) responded to GRB 060502B (Troja et al. GCN 5055). The observations started at 17:26:26 UT (105s after the GRB) by the 0.3m optical telescope with R-band filter located at the AGU campus in Sagamihara, Japan. No new source was found above the 3 sigma limiting magnitude of R~16 calibrated with USNO A2.0 by the preliminary routine analysis on the first 20 frames of image with 5s exposure each. The mean time of the data set corresponded to 319s after the burst. Further analysis is underway.
