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 SWIFT GRB250612.04 (trigger No 1323295,16h 43m 36.72s , -38d 54m 07.2s, R=0.05) errorbox  42 sec after notice time and 83 sec after trigger time at 2025-06-12 01:03:28 UT, with upper limit up to  16.6 mag. The observations began at zenith distance = 36 deg. The sun  altitude  is -42.8 deg. 

The galactic latitude b =  4 deg., longitude l = 345 deg.


Real time updated cover map and OT discovered available here:
