MASTER-OAFA robotic telescope (Global MASTER-Net:
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy,
vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan
National University) was pointed to the GRB191226.02 15 sec after notice
time and 105 sec after trigger time at 2019-12-26 00:32:51 UT. On our
first (20s exposure) set we haven`t found optical transient within Swift
error-box (ra=17.1375 dec=-57.0847 r=0.05).
The 5-sigma upper limit has been about 16.0mag
Error-box Altitude: 62.54
Sun: Altitude: -9.52
Observation and reduction will be continued
