TITLE: GCN CIRCULAR NUMBER: 41349 SUBJECT: EP250812a: Nickel optical upper limit DATE: 25/08/13 18:18:02 GMT FROM: Weikang Zheng at UC Berkeley <weikang@berkeley.edu> Andreas Betz, Riley Patlak, WeiKang Zheng and Alex Filippenko (UC Berkeley) report on behalf of the KAIT GRB team: We observed the field of EP250812a (Zhang et al., GCN 41327) with the 1-m Nickel telescope located at Lick observatory, California. Observations were performed in the R band with 600s x 5 exposures. In our coadd image, we do not detect the optical counterpart (Xin et al., GCN 41340; Ducoin et al., GCN 41342) with an upper limit of R > 20.7 (Vega) at a mid-time of 23.8 hours after the trigger.
