TITLE: GCN CIRCULAR NUMBER: 24316 SUBJECT: LIGO/Virgo S190426c: GROWTH India follow-up DATE: 19/04/28 02:06:16 GMT FROM: Harsh Kumar at Indian Inst of Tech,Bombay G. Waratkar, H. Kumar, V. Bhalerao, V. Karambelkar (IITB), G. C. Anupama, J. Stanzin (IIA) report on behalf of the GROWTH collaboration: We followed up the localization region of the GW candidate event S190426c (LVC et al. GCN 24168) with the GROWTH-India telescope. We obtained 37 r-band overlapping images covering a total area of 12.3 square degrees, with 9.43% probability of containing the GW counterpart. Exposures were 600 seconds long and reached a typical depth of 20.6 magnitude. The field centers (given below) were chosen in coordination with ZTF and DECAM (GCN 24257) to cover the northernmost part of the sky not accessible to them. Data processing is underway. These fields contain 332 galaxies from the GLADE catalog and 6 galaxies from NED. We inspected the NED galaxies (listed below) and do not find any candidate counterparts near them.
