MASTER Global Robotic Net (http://observ.pereplet.ru, Lipunov et al.,2010, Advances in Astronomy, vol.2010, 30L)
observed ANTARES 191011A
(Turley et al. GCN 26005, Ttrig=2019-10-11 15:54:32UT,Tnotice=2019-10-14 14:18:07UT,RA,Dec(2000)=03:19:51.8 +18:48:27 +-0.4d )
at MASTER-IAC and MASTER-Kislovodsk during MASTER own survey.

MASTER didn't receive this alert through usual GCN socket system.

MASTER-IAC robotic telescope   located in Spain, IAC Teide Observatory, 
observed  Antares 191011A alert errorbox during own survey 1 day 24617 sec after trigger time at
2019-10-12 22:44:49 UT, with upper limit up to  18.4 mag on single images .
The observations began at zenit distance = 60 deg. The sun  altitude  was -54.1 deg.

MASTER-Kislovodsk robotic telescope  located in Russia, Kislovodsk Solar Station of Pulkovo observatory,
observed Antares 191011A alert errorbox  1 days 28366 sec after trigger time at 
2019-10-12 23:47:18 UT, with upper limit up to  18.2 mag.
The observations began at zenit distance = 26 deg. The sun  altitude  was -38.6 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.

Also we have a several images (4 square degrees) ~14 hours before trigger 
time at MASTER-IAC with upper limit up to 18.8, made during MASTER own survey.

We obtained the following upper limits:
