(KIAM) report on behalf of larger IKI GRB follow-up collaboration:
We observed DESGW candidates desgw-190814a (AT2019nmd), desgw-190814b
(AT2019nme) (Soares-Santos et al., GCN 25336) of the NSBH event
S190814bv (The LIGO/Virgo Scientific Collaboration GCNs 25333, 25324)
with AS-32 (0.7m) telescope of Abastumani Observatory starting on Aug.
16 (UT) 00:12:54. We obtained several 60 s exposures in R-filter per
each candidate.
In particular we do not detect the desgw-190814b (AT2019nme).
Photometry of the field is following
Name, TNS Name, MJD, Exposure (s), R_upper_limit (mag)
desgw-190814b, 2019nme, 58711.03464, 12*60, 18.8
and based on nearby USNO-B1.0 stars (R2 magnitudes).
