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 GRB 240929A ( Fermi GBM team, GCN 37627) errorbox 21 sec after notice time and 55 sec after trigger time at 2024-09-29 19:50:59 UT, with upper limit up to 17.9 mag. The observations began at zenith distance = 32 deg. The sun altitude is -43.0 deg.
The galactic latitude b = 13 deg., longitude l = 119 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2619216
We obtain a following upper limits.
