MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the Swift GRB 241213A ( R. Gupta et al., GCN 38547) errorbox 1183 sec after notice time and 1208 sec after trigger time at 2024-12-13 02:39:08 UT, with upper limit up to 17.8 mag. The observations began at zenith distance = 38 deg. The sun altitude is -20.1 deg.
The galactic latitude b = 26 deg., longitude l = 185 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2708197
We obtain a following upper limits.
Tmid-T0 | Site |Filt.| Expt. | Limit| Comment _________|_____________________|_____|_______|______|________
