During a MASTER-net inspect of LIGO/Virgo S191216ap (Lipunov et al., GCN
26457) MASTER-Amur robotic telescope (Global MASTER-Net:
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy,
vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical
University) started inspect of the LIGO/Virgo S191216ap IceCube neutrino
counterpart errorbox (GCN 26460,26463) 41727 sec after trigger time at
2019-12-17 09:17:25 UT, with upper limit up to 17.4 mag. Observations
started at twilight. The observations began at zenith distance = 50 deg.
The sun altitude is -16.2 deg.
MASTER-Tunka robotic telescope located in Russia (Applied Physics
Institute, Irkutsk State University) started inspect of the LIGO/Virgo
S191216ap IceCube neutrino counterpart errorbox 44823 sec after
trigger time at 2019-12-17 10:09:01 UT, with upper limit up to 19.0 mag.
Observations started at twilight. The observations began at zenith
distance = 50 deg. The sun altitude is -10.0 deg.
MASTER OF J212806.11+023221.9s - Optical Flare known CV.
MASTER-Tunka auto-detection system ( Lipunov et al., "MASTER Global
Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OF at (RA, Dec) = 21h 28m 06.11s +02d 32m 21.9s on
2019-12-17.43984 UT.
This flash falls off with the position of the famous CV CSS 151110: 212806
+ 023221 (U Gem type).
The OT magnitude in 'C' filter is 17.0m
(mlim18.3=).
The OT is seen in 2 images. There is no minor planet at this place.
We have reference image on 2010-08-29.64730 UT with unfiltered mlim=
18.8m.
Spectral observations are required.
Real time updated cover map and OT discovered available here:
