MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea
astronomical station) was pointed to the FERMI TRIGGER_NUM: 564485824
(possible GRB 181121.40) 1 days 61648 sec after trigger time at 2018-11-23
02:44:28 UT, with upper limit up to 19.1 mag. The observations began at zenit
distance = 79 deg. The sun altitude is -21.8 deg.
MASTER-Tavrida auto-detection system discovered possible OT source at (RA, Dec)
= 17h 17m 38.71s +56d 56m 48.7s on 2018-11-23.87034 UT. Error is about 2
arcsec.
The OT unfiltered magnitude is 17.7m (3 sigma limit 18.0 m).
The OT is inside the large IPN box formed by intersection of the
Fermi-INTEGRAL triangulation annulus and the Fermi-GBM 3 sigma final
position (D. Svinkin, private communication).
The OT is seen in 2 images. There is no minor planet at this place.
We have reference image without OT on 2017-10-04.75208 UT with unfiltered
magnitude limit 19.0m.
The OT offset are 10.3E and 36N arc sec from center of the PGC3135767 galaxy.
The distance to the Galaxy is about 120 Mpc for H = 70 km/s/Mpc .
The absolute OT magnitude for this distance is about -17.8 .
We reobserved this error-box in MASTER-Kislovodsk with mlim=20.4 , starting on
2018-11-26 16:17:29UT (1980s exp). We can not exclude OT m ~ 20.5 mag.
MASTER-Amur robotic telescope (MASTER-Net: http://observ.pereplet.ru, Lipunov
et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia
(Blagoveshchensk State Pedagogical University) was pointed to the FERMI
GRB181121.4 ( 16h 45m 52.80s , +37d 34m 48.00s, R=8) 43375 sec after trigger
time at 2018-11-21 21:39:54 UT, with upper limit up to 17.4 mag. Observations
started at twilight. The observations began at zenit distance = 67 deg. The
sun altitude is -11.6 deg.
MASTER-Tunka robotic telescope located in Russia (Applied Physics Institute,
Irkutsk State University) was pointed to the FERMI GRB181121.4 1 days 4810 sec
after trigger time at 2018-11-22 10:57:09 UT, with upper limit up to 18.2 mag.
Observations started at twilight. The observations began at zenit distance =
54 deg. The sun altitude is -16.1 deg.
MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU,
Kislovodsk Solar Station of Pulkovo observatory) was pointed to the FERMI
GRB181121.4 2 days 18064 sec after trigger time at 2018-11-23 14:38:04 UT, with
upper limit up to 18.7 mag. Observations started at twilight. The
observations began at zenit distance = 54 deg. The sun altitude is -10.4 deg.
MASTER-IAC robotic telescope located in Spain (IAC Teide Observatory) was
pointed to the FERMI GRB181121.4 4 days 34252 sec after trigger time at
2018-11-25 19:07:51 UT, with upper limit up to 17.9 mag. Observations started
at twilight. The observations began at zenit distance = 69 deg. The sun
altitude is -13.4 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.
