TITLE: GCN CIRCULAR NUMBER: 16448 SUBJECT: GRB 140622A: iTelescope.Net T11 Optical Observation DATE: 14/06/24 11:00:15 GMT FROM: Takanori Sakamoto at AGU D. Kawamura, T. Sakamoto, A. Yoshida (AGU) We observed the field of GRB 140622A detected by Swift (trigger #602278; D'Elia et al., GCN Circ. 16433) with the iTelescope.Net (http://www.itelescope.net) T11 (0.51 m Planewave) telescope located at the New Mexico Skies Observatory (NM, USA). 60 images of 60 sec exposures were taken in the R filter starting from June 22 09:50:33 (UT) about 14.5 minutes after the trigger and stopped on June 22 11:01:25 (UT). We do not detect the optical afterglow both in the individual images and the stacked image at the enhanced X-ray afterglow position (Osborne et al., GCN Circ. 16434). The estimated five sigma upper limit of the combined image (total exposure of 3600 sec) is ~18.5 using the USNO-B1 catalog.
