Нашёл таблицу наблюдений гамма-всплесков Swift GRB Table

•The most recent 50 of 622 bursts are displayed here.

Там упоминаются 2 наших телескопа - ISON-NM в Нью-Мексико (три раза) и GAS-250 в Уссурийске.
Также встречаются ЗТШ, АЗТ-33ИК, АЗТ-14 (видимо, тоже Монды), АЗТ-22 на Майданаке, и русско-турецкий 1,5-м телескоп RTT150, АЗТ-11 в Кампо-Императоре.

Цейсс-2000 - это, видимо, Терскол. Есть еще загадочная RAS Observatory.

Почему-то МАСТЕР упоминается всего лишь 3 раза. Вот тебе и сеть для наблюдения гамма-всплесков.  В замешательстве

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

We observed the field of the Swift GRB 170705A (Starling et al. GCN
21289) which is also detected by GBM/Fermi and Konus-Wind  (Bissaldi  et
al., GCN 21297; Svinkin et al., GCN 21299)  with Zeiss-1000 1-m
telescope of Tien Shan Astronomical Observatory
on July 6-8.  We took
several images in R-filter.  The optical afterglow  of GRB 170705A
(Starling et al. GCN 21289, Lipunov et al. GCN 21291, Butler et al. GCN
21293, Emery et al. GCN 21294; Ugarte Postigo et al. GCN 21298)  is
visible in a combined image on July 6, and upper limit only for July
7-8. Preliminary  photometry of the afterglow is following.

Inasaridze (AbAO), E. Mazaeva (IKI), V. Agletdinov (KIAM),   V. Ayvazian
(AbAO),  O. Kvaratskhelia (AbAO), G. Inasaridze (AbAO),    I. Molotov (KIAM)
report on behalf of  larger GRB follow-up collaboration:

We observed the field of the Swift GRB 170711A (D'Elia  et al. GCN 21321)
with K-800 (0.8m) telescope  of  ISON/Terskol observatory starting on July,
12 (UT) 00:00:39 and  AS-32 telescope of AbAO starting  on July, 11 (UT)
23:58:46, i.e. about 1.6 hours after GRB trigger.  We obtained
several unfiltered images. We do not detect any source in stacked images
within the enhanced XRT position (Beardmore  et al. GCN 21323).
Preliminary  photometry of the field is following

Date       UT start  t-T0                 Filter   Exp.      OT     Err.  UL

                      (mid, days)                         (s)

2017-07-12   00:00:39 0.07658 CR      45*25 n/d n/d  19.1     K-800

Photometry is based on nearby stars of USNO-B1.0

1378-0084262   15.13

We detect the object in  coordinates (J2000)  03 03 11.46  +47 50 56.1  (+/-
0.5 arcsec) which is 7.7 arcsec apart from a center of the enhanced XRT
position. The object is clearly detected in the stacked image of K-800  and
marginally seen at  the same position with AS-32 stacked image. The
brightness of the object is 18.56 +/- 0.25 based on the reference stars
listed above. The object is absent in the  USNO-B1.0. At present, it is not
clear whether this object has any relation to the GRB 170711A.

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

We observed the field of the Swift GRB 170728B (Cenko et al., GCN 21371)
with Zeiss-1000 of SAO RAS (July 29, August 4,5 ), AS-32 telescope of AbAO
(July 29) and  Zeiss-1000  telescope of Tien Shan Astronomical Observatory
(July  30,31 August 1,6).  Below we report the photometry of the optical
afterglow (D'Avanzo et al., GCNs 21372, 21373; Heintz  et al., GCN 21374;
Guidorzi   et al., GCN 21375) and upper limits of our observations.
Preliminary photometry is following:

Coordinates of the afterglow obtained from observation on July 30 are
(J2000)
15 51 55.5179 +70 07 21.123  with uncertainties on both coordinates of  0.2
arces which is compatible with coordinates of TNG (D'Avanzo et al., GCN
21373) and VLA (Fong  et al., GCN 21395). The  finding chart can be found in
http://grb.rssi.ru/GRB170728B/GRB170728B_TShAO_R_170730.png

The light curve of the afterglow based on  observations above and photometry
reported in GCNs (Dintinjana et al., GCN 21394; Watson GCN 21389;   D'Avanzo
et al., GCN 21372; Heintz  et al., GCN 21374; Guidorzi   et al., GCN 21375)
can be found in
http://grb.rssi.ru/GRB170728B/GRB170728B_lc+GCNs_v2.png
Based on our observation on July, 30 (~ 1.8 days after burst onset) one can
suggest that the OT experienced  rebrightening at that epoch.

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

We observed the field  of the Fermi/LAT-detected burst GRB 171124A
(Longo et al. GCN   22156) with Zeiss-1000 1-m telescope of Tien Shan
Astronomical Observatory starting on Nov. 27 (UT) 12:28:32. We took
several images in R-filter with exposures of 120 s. We cover all LAT-
localization region.
The three XRT sources ## 1,3,4 (Osborne  et al. GCN   22165)  are
detected in our stacked image. These sources are also presented in the
USNO-B1.0 catalogue. We do not detect any optical object within X-ray
afterglow (XRT #2 error circle, Osborne  et al. GCN  22174).  We may
note that 4.5 arcsec South of XRT #2    we detect a galaxy which is also
present in USNO-B1.0.

Preliminary photometry of the field is following:

We observed the field of GRB 180205A (Evans  et al., GCN 22381) with
AS-32 (0.7m) telescope of Abastumani Observatory starting on Feb., 06
(UT)  23:53:51. We obtained several unfiltered images  starting on Feb.
05 (UT) 12:54:29.  The afterglow of GRB 180205A (Evans et al., GCN

follow-up collaboration:

We observed the field of the MAXI J1813-095 source (trigger=811167; ATel
#11323 Kawase et al.) with AS-32 (0.7m). We obtained several unfiltered
images  starting on Feb. 22 (UT) 01:40:27. We do not detect any evident
object within XRT error circle (Beardmore  et al., GCN 22431). The only
one object which is visible in POSS2 in coordinates  (J2000) 18:13:33.84
  -09:31:54.5 +/-0.8 is also visible in our combined image. The
magnitude of the source is 18.92 +/- 0.12 and calibrated against nearby
USNO-B1.0 stars.
