In response to the LIGO/Virgo binary neutron star candidate G298048 on
Aug 17 (GCNC 21509), we used the JGT 0.6m robotic telescope at the
BOOTES-5 station at Observatorio Astron��mico Nacional de San Pedro M��rtir (M��xico)
to image the 15 galaxies in the GLADE Catalogue (GCN 21516) starting on
Aug 18.21 UT. The potential optical candidate (GCN 21529) was only
imaged on Aug 19.21 UT, with the images quality being affected by the
very high airmass and the twilight sky. The optical candidate (SSS17a) is
only barely visible in the outskirts of the NGC 4993 galaxy. A more
detailed analysis of the data is in progress.
