A. Volnova (IKI), A.V. Kusakin (Fesenkov Astrophysical Institute)  A.V.
Khruslov (INASAN), A. Pozanenko (IKI) report on behalf of larger GRB
follow-up collaboration:

We observed the optical afterglow (Elenin et al., GCN 16143; Kaur et
al., GCN 16144; Ferrante et al., GCN 16145; Chester et al., GCN 16147;
Maehara et al., GCN 16151) of the Swift GRB 140423A (Sonbas et al.,
GCN 16142) with Zeiss-1000 (East) 1m telescope of Tien Shan Astronomical
Observatory on Apr., 23 and Apr., 24. We took several images in R-filter
of 300 and 540 s  exposures in three epochs.

Details of the photometry are following:

date        UT start   t-T0       Filter  Exp.  OT
                       (mid, days)          (s)
2014-04-23 R 15:04:19  0.291036   R     8*300  20.47 0.14
2014-04-23 R 19:04:44  0.450758   R     6*300  20.70 0.20
2014-04-24 R 15:20:01  1.322830   R    12*540  22.17 0.10

The photometry is based on  SDSS stars, R (gri -> R transformations by
Lupton 2005):

SDSS id                      R
J130914.51+494636.5   18.661+/-0.019

J130924.79+494946.6   19.533+/-0.038

The light curve of the afterglow based on our previous an later
observations (GCNs  16143, 16148, 16168, 16247, 16264) can be found in

V. Rumyantsev (CrAO), A. Pozanenko (IKI) report on  behalf of larger GRB
follow-up collaboration:

We observed the field of the Swift GRB 140824A (Beardmore  et al., GCN
16732) with ZTSh telescope of CrAO observatory starting on Aug. 24 (UT)
17:48:55 (9.1 hours after burst trigger). We took several images in
R-filter of 120 s exposure. Within  enhanced XRT position (Evans et al.,
GCN  16735) we do  not detect any source. Photometry of a combined image
is following

Date        UT start,  t-t0     Filter   Exp.   OT      UL (3 sigma)
                       (mid, days)        (s)

2014-08-24 17:48:55    0.4105   R        39x120 n/d     23.5

The photometry is based on USNO-B1.0  star
1233-0239576 (13:46:31.55 +33:18:14.7) assuming R=19.66
