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 15954Not found
 
 
; 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.
