LIGO/Virgo G299232: GRAWITA Asiago/Copernico Telescope observations
Abstract
We observed the field of the Optical Transient Discovery by Swift/UVOT (LVG GCN 21733) with the Asiago 1.82 m Copernico Telescope equipped with AFOSC under poor sky conditions. We do not detected the Swift OT down to the following limits: Filter (SDSS) average UT total Exp (s) limit (ABmag) u 20170828.90 1800 22.5 g 20170828.89 270 21.6 r 20170828.88 270 20.8 i 20170828.93 270 21.9 z 20170828.92 900 21.4 We note the presence of the galaxy UGC 1178 at about 5 arcmin from the position of the OT. This galaxy has a redshift z=0.018399, and the projected distance of the OT seen by UVOT would then correspond to about 120 Kpc from the galaxy center. [GCN OPS NOTE(29aug17): Per author's request, The Subject-line was changed from "...INAF Asiago/Copernico..." to "...GRAWITA Asiago/Copernico...". And the the last paragraph "UGC 1178a" was changed to "UGC 1178".
