TITLE: GCN CIRCULAR NUMBER: 15974 SUBJECT: GRB 140311A: Kottamia I-band observation DATE: 14/03/12 19:43:56 GMT FROM: Michitoshi Yoshida at HASC,Hiroshima U M. Yoshida, R. Itoh, Y. Moritani (HASC, Hiroshima Univ.), G. B. Ali, A. Essam, A. Takey, and G. Hamed (NRIAG, Egypt) We report the I-band photometry of GRB 140311A. The observation was performed with the Newtonian camera of the 188cm telescope at Kottamia observatory just before the R-band observation reported by Yoshida et al. (GCN 15954; 15957). We started the I-band observation at 21:57:30 UT on Marth 11 2014; 0.8706 hours after the trigger. Photometric result of the source is shown below. We used the nearby star NOMAD1 0906-0229809 for flux calibration.
