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
