TITLE: GCN CIRCULAR NUMBER: 11455 SUBJECT: XRF 101117A, RIMOTS optical upper limits DATE: 10/12/14 12:30:56 GMT FROM: Norisuke Ohmori at Miyazaki U M. Akiyama, N. Ohmori, A. Daikyuji, Y. Nishioka, K. Noda, T. Kuramaru, M. Yamauchi (University of Miyazaki) We have observed the field covering the error circle of XRF101117A (MAXI trigger, GCN 11410, Yamazaki et al.) with the unfiltered CCD camera on the 30-cm telescope at University of Miyazaki. The observation was started 18:16:09 UT (about 10.7 hr after the MAXI trigger time) on the condition with a little cloud. We have compared our data of 30 sec exposures with the USNO-A2.0 catalog. There is no new source at the reported position. (GCN 11410, K. Yamazaki et al. GCN 11418, S. B. Cenko) the upper limits are as follows: --------------------------------------------------------------- Start(UT) End(UT) Num. of frames Limit (mag.) --------------------------------------------------------------- 18:16:09 18:17:12 1 16.6 18:16:09 18:50:08 15 16.8 ---------------------------------------------------------------
