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 EP250302a ( EP Team et al., GCN 39556) errorbox 328 sec after notice time and 57360 sec after trigger time at 2025-03-03 07:32:04 UT, with upper limit up to 19.8 mag. The observations began at zenith distance = 73 deg. The sun altitude is -35.3 deg.
The galactic latitude b = 70 deg., longitude l = 190 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2797947
We obtain a following upper limits.
Tmid-T0 | Date Time | Site | Coord (J2000) |Filt.| Expt. | Limit| Comment _________|_____________________|_____________________|____________________________________|_____|_______|_______|________
