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 GRB231110.89 (trigger No 1195733,23h 45m 11.04s , +82d 37m 15.6s, R=0.05) errorbox 47 sec after notice time and 548 sec after trigger time at 2023-11-10 21:28:43 UT, with upper limit up to 18.7 mag. The observations began at zenith distance = 43 deg. The sun altitude is -26.1 deg.
The galactic latitude b = 20 deg., longitude l = 121 deg.
Real time updated cover map and OT discovered available here:

We obtain a following upper limits.
Tmid-T0 | Site |Filt.| Expt. | Limit| Comment

579 | MASTER-Tunka | C | 60 | 18.7 |
658 | MASTER-Tunka | C | 60 | 18.7 |
737 | MASTER-Tunka | C | 60 | 18.7 |
Filter C is a clear (unfiltred) band.
The observation and reduction will continue.
