Yoshida (AGU) \n\nWe observed the field of GRB 150211A detected by Swift (trigger #630714; \nStarling et al., GCN Circ. 17434) with the iTelescope.Net (http://www.itelescope.net) \nT11 (0.50 m Plane Wave) telescope located at the New Mexico Skies Observatory (NM, USA).  \n20 images of 60 sec exposures were taken in the R filter starting from February 11 12:06:11 (UT) \nabout 14.3 minutes after the trigger and stopped on February 11 12:32:17 (UT).  \nWe do not detect the optical afterglow both in the individual images and the stacked image \nat the enhanced X-ray afterglow position (Starling et al., GCN Circ. 17442).  The estimated \nfive sigma upper limit of the combined image (total exposure of 1200 sec) is ~19.1 using \nthe USNO-B1 catalog.",
