Yoshida (AGU)\n\nWe observed the field of GRB 140430A detected by Swift (trigger #597722; \nSiegel et al., GCN Circ. 16190) with the iTelescope.Net (http://www.itelescope.net) \nT16 (15 cm Takahashi TOA-150) telescope located at the AstroCamp Observatory \n(Nerpio, Spain).  \n\nDue to the elevation constraint, we were able to collect only 4 images of 60 sec \nexposures in the R filter starting from April 30 20:46:42 (UT) about 13 minutes \nafter the trigger and stopped on April 30 20:52:42 (UT).  We do not detect the optical afterglow \nboth in the individual images and the stacked image at the reported optical \nafterglow position (Siegel et al., GCN Circ. 16190; Malesani et al., GCN Circ. 16193).  \nThe estimated five sigma upper limit of the combined image (total exposure of 240 sec) \nis ~18.6 using the USNO-B1 catalog.",
