Yoshida (AGU) \n\nWe observed the field of GRB 150203A detected by Swift (trigger #629578; \nUkwatta et al., GCN Circ. 17377) 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 3 \n4:22:11 (UT) about 13.3 minutes after the trigger and stopped on February 3 4:47:29 (UT).  \nWe do not detect the optical afterglow both in the individual images and the stacked \nimage at the enhanced X-ray afterglow position (Evans et al., GCN Circ. 17378).  \nThe estimated five sigma upper limit of the combined image (total exposure of 1200 sec) \nis ~18.9 using the USNO-B1 catalog.",
