MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) was pointed to the Swift GRB 241115A ( M. A. Williams et al., GCN 38235) errorbox 2802 sec after notice time and 2828 sec after trigger time at 2024-11-15 14:05:33 UT, with upper limit up to 16.4 mag. The observations began at zenith distance = 83 deg. The sun altitude is -44.1 deg.
The galactic latitude b = -14 deg., longitude l = 206 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2671057
We obtain a following upper limits.
Tmid-T0 | Site |Filt.| Expt. | Limit| Comment _________|_____________________|_____|_______|______|________
2831 | MASTER-Tunka | C | 5 | 14.0 | 2871 | MASTER-Tunka | C | 5 | 13.8 | 2888 | MASTER-Tunka | C | 5 | 13.9 | 3335 | MASTER-Tunka | C | 1 | 13.7 | 3348 | MASTER-Tunka | C | 1 | 13.3 | 5552 | MASTER-Tunka | C | 60 | 16.4 | Coadd Filter C is a clear (unfiltred) band.
The observation and reduction will continue. The message may be cited.
