We observed the Swift GRB 160131A (Page et al., GCN 18951) with
Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory.
We obtained several images in R filter on Feb. 06 and Feb. 07.The

(Research Center of Astronomy and Geophysics MAS),   I. Molotov (KIAM),
 A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration:

We observed the field of INTEGRAL and Fermi GRB 160223B GRB 160223B (Gotz et
al. GCN 19059; von Kienlin et al., GCN 19061) with ORI-40 telescope of
Khureltogot observatory starting on Feb., 23 (UT) 12:34:31.  Within 2.2
arcmin error circle of the GRB 160223B localization  (Gotz   et al., GCN
19059) we marginally detect two possible sources not presented in USNO-B1.0
catalog. Coordinates of the sources are

Source (1): (J2000) 6:20:05.53 +33:24:58.7
Source (2): (J2000) 6:20:03.89 +33:23:14.2

with uncertainties of 1 arcsec in both coordinates.
At this time we cannot confirm the sources are real  or variable due to low
S/N and absence of a full dataset.

Preliminary photometry of the sources is following

SUBJECT: GRB 160625B: TSHAO optical observations
DATE:    16/07/11 12:56:47 GMT
FROM:    Alexei Pozanenko at IKI, Moscow

E. Mazaeva (IKI), A. Kusakin (Fesenkov Astrophysical Institute), P.
Minaev (IKI), I. Reva (Fesenkov Astrophysical Institute), A. Volnova
(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 on July
8 and 10. 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

FROM:    Alexei Pozanenko at IKI, Moscow

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

We observed the field of GRB 160801A  (D'Elia et al., GCN 19744 ) with
Zeiss-1000 (East) 1-m telescope of Tien Shan Astronomical Observatory. We
obtained several images in R filter starting on August 01 (UT) 15:10:55. We
do not  detect any optical source within enhanced XRT error position (Goad
et al., GCN 19746). Preliminary photometry of a combined image is following

Date              UT start   t-T0    Filter  Exp.   OT     Err.  UL
                                       (mid, days)     (s)

2016-08-01 15:10:55  0.28422  R   60*120 n/d  n/d  22.4

Photometry is based on nearby SDSS DR9 stars
SDSS-DR9_id                   R(Lupton)
J141100.70+132838.3    17.993
J141057.03+132833.7    17.684

J141102.35+133019.9    18.384
J141102.64+133004.5    18.354

Our preliminary  photometry of the SDSS object (Cano et al.,  GCN 19753)
which is also mentioned by Moskvitin et al. (GCN 19755)  is R=21.1+/-0.1 and
based on the same nearby SDSS stars.
