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) started inspect of the Fermi GRB240901.95 (trigger No 746923430,22h 35m 00.00s , +65d 00m 00.0s, R=25.78) errorbox 4838 sec after notice time and 4869 sec after trigger time at 2024-09-02 00:04:54 UT, with upper limit up to 19.3 mag. The observations began at zenith distance = 30 deg. The sun altitude is -28.9 deg.
The galactic latitude b = 6 deg., longitude l = 109 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2585018
We obtain a following upper limits.
