MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) was pointed to the Swift GRB 200711A ( F. E. Marshall et al., GCN 28078) errorbox 26829 sec after notice time and 26854 sec after trigger time at 2020-07-11 18:32:11 UT, with upper limit up to 15.9 mag. Observations started at twilight. The observations began at zenith distance = 59 deg. The sun altitude is -10.2 deg.
MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the Swift GRB 200711A errorbox 26939 sec after notice time and 26964 sec after trigger time at 2020-07-11 18:34:00 UT, with upper limit up to 16.7 mag. Observations started at twilight. The observations began at zenith distance = 54 deg. The sun altitude is -15.0 deg.
The galactic latitude b = -3 deg., longitude l = 35 deg.
Real time updated cover map and OT discovered available here:
We obtain a following upper limits.
Tmid-T0 | Site |Filt.| Expt. | Limit| Comment
26945 | MASTER-Tavrida | C | 180 | 15.9 |
26994 | MASTER-Kislovodsk | C | 60 | 16.7 |
Filter C is a clear (unfiltred) band.
The observation and reduction will continue.
