LIGO/Virgo G299232: continued WHT observations of the field of SwiftJ014008.5+343403.6
Abstract
On Aug, 30, 2017, starting at 04:54 (UTC), we obtained r',i', and z'-band images with an exposure time of 3x600, 600, and 600 sec, respectively, with the ACAM instrument mounted on the William Herschel Telescope on La Palma (Spain) of the optical transient reported by Emery et al. GCN21733. Seeing conditions were mediocre with values as large as 2". We do not detect a source at the reported position down to an SDSS-based AB limiting magnitude of r', i', z' > 23.5, 21.5, 20.3 based on the faintest sources detected in the field.
