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

TITLE:   GCN CIRCULAR
NUMBER:  20442
SUBJECT: GRB 161219B: afterglow and SN2016jca optical observations
DATE:    17/01/12 17:57:30 GMT
FROM:    Alexei Pozanenko at IKI, Moscow

A. Volnova (IKI), E. Mazaeva (IKI), R. Inasaridze (AbAO), A. Moskvitin (SAO
RAS), E. Klunko (ISTP), V. Rumyantsev (CrAO), I. Korobtsev (ISTP),   V.
Ayvazian  (AbAO),  O. Kvaratskhelia  (AbAO), G. Inasaridze (AbAO),  I.
Molotov (KIAM), A. Pozanenko (IKI)    report on behalf of  larger GRB
follow-up collaboration:

We observed the field of GRB 161219B (Swift trigger 727541; D'Ai,GCN 20296)
with AZT-33IK (Mondy), ZTSh (CrAO), AS-32 (AbAO) and Zeiss-1000 (SAO RAS)
telescopes.  We obtained  unfiltered images (AbAO) and images in R-filter
(other observatories). The optical source associated with the afterglow
(D'Ai et al., GCN 20296; Kruehler et al., GCN 20299; Guidorzi et al., GCN
20300; Martin-Carrillo et al., GCN 20305) and SN2016jca  (de Ugarte Postigo
et al., GCN 20342; Chen et al., GCN 20380) is clearly visible in all our
observations.

Preliminary light curve of the afterglow and  SN2016jca  can be found at
http://grb.rssi.ru/GRB161219B/GRB161219B_LC.png
Photometry is based on nearby USNO-B1.0 stars (R2) common for all images.
Late time photometry is contaminated by  Pan-STARRS galaxy previously
reported by Kruehler et al. (GCN 20299), and  also presented in USNO-B1.0.
Apparent maximum brightness of the SN2016jca was observed at about 11 days
after burst onset (R = 19.2 at 2016-12-30 (UT) 20:04:59) and actual SN peak
could be slighter later,  between 11 and 14 days after burst.

We observed the field of short GRB 170112A (Mingo  et al., GCN 20436)
with AS-32 (0.7m) telescope of Abastumani Observatory  on Jan., 12 (UT)
15:35:30. We obtained several unfiltered images of the field. Within BAT
error circle (Mingo  et al., GCN 2043) we found the source which is
absent in USNO-B1.0 at coordinates (J2000) 01:00:49.80  -17:10:17.5 with
uncertainty of 0.9 arcsec in both coordinates.

We observed the field of optical transient reported by Lipunov et al. (GCN
20502) as a possible candidate of the Fermi/GBM GRB 170121B (Hamburg et al.
GCN Circ. 20505) and XRT  afterglow  candidate reported by Sbarufatti  et

starting on Jan., 23 (UT)  16:14:49. We obtained several unfiltered images
of the field.  We do not find any source at coordinates of the optical
transient (Lipunov et al., GCN  20502). Within XRT error circle  (Sbarufatti
et al., GCN  20510) we find the source which is also presented in DSS2 and
USNO-B1.0 as the star USNO-B1.0 0807-0048671 (magnitudes R1 = 17.94, R2 =

NUMBER:  20978
SUBJECT: GRB 170325A: optical observations, possible OT/host detection
DATE:    17/04/04 20:20:06 GMT
FROM:    Alexei Pozanenko at IKI, Moscow

E. Mazaeva (IKI), A. Pozanenko (IKI), V. Rumyantsev (CrAO), P. Minaev
(IKI),  E. Klunko (ISTP), A. Volnova (IKI), M. Eselevich (ISTP)   report
on behalf of larger GRB follow-up collaboration:

Цe followed up the short GRB 170325A (Palmer et al., GCN  20938) with
AZT-33IK telescope of Sayan observatory (Mondy) an ZTSh telescope of
CrAO observatory
. The burst was detected by GBM/Fermi (Bissaldi et al.,
GCN 20940) and also detected as 5.5 sigma non-triggered IBAS event of
0.1 s duration of SPI-ACS/INTEGRAL (see
http://grb.rssi.ru/GRB170325A/GRB170325_SPI-ACS.png).

We obtained several images in R-filter  on  March 26, March 29, and
April 1 and cover all 90% error box of the BAT/Fermi (Palmer et al., GCN
  20938).  We investigated variability of sources in the BAT/Fermi error
box between the three epochs. One source exhibits marginal fading
between first and second epochs. Preliminary photometry of the source is
following

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

2017-04-01 15:46:59  7.35072  R      4100    22.45   0.25  22.6

the photometry is based on nearby SDSS-DR9 stars

SDSS-DR9_id         R(Lupton transformations)

J083002.05+203031.2 16.74
J082950.18+203013.8 18.25
J082949.90+203106.9 16.65

Coordinates of the source are  (J2000) 08:29:57.677   +20:30:51.75 with
uncertainty of  0.7 arcsec in both coordinates. The finding chart can be
found in
http://grb.rssi.ru/GRB170325A/GRB170325A_Mondy_170326_2.png
http://grb.rssi.ru/GRB170325A/GRB170325A_CrAO_170329.png

The source is not presented in SDSS-DR9, but clearly visible in
r(=22.59), i(=22.10) filters, barely visible in u-filter (23.1), and not
detected in g and z of SDSS images.

We suggest the source is an afterglow and host candidates of the short
GRB 170325A.

(AbAO), G. Inasaridze (AbAO), I. Molotov (KIAM), report on behalf of
larger GRB follow-up collaboration:

We observed the field of the SWIFT trigger 748858 (Siegel, et al., GCN
21011) with AS-32 (0.7m) telescope of Abastumani Observatory and with
Zeiss-1000 1-m telescope of Tien Shan Astronomical Observatory. In each
observation we fully cover both BAT error circles, initial (Siegel  et
al., GCN 21011) and ground-calculated error circle (Sakamoto  et al.,
GCN 21017). Within  ground-calculated error circle we do not find any
new source in comparison with SDSS catalog.  Within  XRT error circle of
the source reported in GCN 21017 (Sakamoto  et al.) we find the source
which is already mentioned by (Butler et al., GCN 21026). The source
coincides with the star  of J131924.35+153001.6 and has the brightness
of R =19.53 +/- 0.04 according to  SDSS DR9 and Lupton gri -> R
transformations.

Limiting magnitudes as well as the brightness of the star
J131924.35+153001.6 for each observation are presented below.
