Buckley (SAAO) report on behalf of IKI-FuN follow-up collaboration:
We observed the MASTER OT J063515.49-624002.9 (Chasovnikov et al., GCN
23520) of Fermi trigger 565936249 with 1m telescopes of SAOO observatory.
Observation started on Dec. 08 (UT) 21:55:48 in R-filter. We detected
optical transient (Chasovnikov et al., GCN 23520). Preliminary photometry
is following

The optical transient has faded since its discovery. The optical transient
located at 4.59 degrees from Fermi-GBM Final Position, and ~1 arcsec from
USNOB-1.0 object 0273-0095603 098.814192 -62.667439 (R=20.98).
