(KIAM) report on behalf of larger IKI GRB follow-up collaboration:

We observed  DESGW candidates desgw-190814a (AT2019nmdNot found
 
 
), desgw-190814b 
(AT2019nmeNot found
 
 
) (Soares-Santos et al., GCN  25336Not found
 
 
) of the NSBH event
  S190814bv (The LIGO/Virgo Scientific Collaboration GCNs 25333Not found
 
 
, 25324Not found
 
 
) 
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  (AT2019nmeNot found
 
 
). 
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).
