Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory.
We obtained several images in R filter starting on August 04 (UT)

19770), Moskvitin et al. (GCN 19771), Xu et al. (GCN #19773) and Bolmer

We observed the field of GRB 160824A (Evans   et al., GCN 19855)  with K-800
(0.8m f/2.9)   telescope  of ISON/Terskol   observatory. We obtained several
unfiltered images starting on  August 24 (UT) 23:58:36.  We detected
optical source in coordinates
(J2000) 05:20:21.18 +40:01:43.5 with uncertainty of 1 arcsec in both
coordinates. This is 2.6 arcsec apart of the center of the enhanced XRT
error circle (Goad et al., GCN 19857).  At this time we cannot say nothing
about variability of the object.  It is not clear whether our source is the
same as the source reported by Marshall et al. (GCN 19860).  Preliminary

Volnova (IKI),   I. Molotov (KIAM)  report on behalf of  larger GRB
follow-up collaboration:

We observed the field of GRB 161219B (Swift trigger 727541; D'Ai,
GCN 20296) with K-800 (0.8m) telescope  of ISON/Terskol   observatory
starting  on December, 19 (UT) 18:57:51, i.e. about 9 minutes after GRB
onset.  We obtained several unfiltered images of 30 s exposure. The
optical afterglow (D'Ai et al., GCN 20296; Kruehler et al., GCN 20299;
Guidorzi et al., GCN 20300; Martin-Carrillo et al., GCN 20305) is
clearly visible in separate images. Preliminary light curve of the
afterglow can be found in

E. Mazaeva (IKI),  I. Reva (Fesenkov Astrophysical Institute), A.
Kusakin (Fesenkov Astrophysical Institute), A. Volnova (IKI), A.
Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration:

We observed the field of GRB 161224A  (Swift trigger=728268,
Cholden-Brownet al., GCN 20333) with Zeiss-1000 (East) 1-m telescope of
Tien Shan Astronomical Observatory. We obtained several images in R
filter starting on Dec. 25 (UT) 00:13:31 and Dec. 25 (UT) 23:45:12. We
do not detect any evident variable source in the BAT ground-calculated
position (Ukwatta  al., GCN 20337). Within enhanced XRT position
(Cholden-Brownet al., GCN 20338) we not detected any source. Preliminary
photometry of the field is following
