A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration:
Corrected text of the GCN 19619 (Mazaeva et al.) should be as follows.

(IKI), A. Pozanenko (IKI) report on behalf of larger GRB follow-up
collaboration:
We observed the field of GRB 160625B (Dirirsa et al., GCN 19580; Burns
et al. GCN 19581) with Zeiss-1000 (East) 1-m telescopes of Tien Shan
Astronomical Observatory. We obtained several images in R filter
starting on June 28 (UT) 18:12:30. We detect optical afterglow of GRB
160625B (Troja et al., GCN 19588; Oates et al., GCN 19589).
Preliminary photometry of a combined image is following

2016-06-28 18:12:30 2.86135 R 63*120 20.32 0.06 22.7
Photometry is based on nearby USNO-B1.0 stars reported in GCN 19605
(Mazaeva et. al).
