Fermi GRB 241002B: Global MASTER-Net observations report

MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB 241002B ( Fermi GBM team, GCN 37668) errorbox 109 sec after notice time and 140 sec after trigger time at 2024-10-02 06:16:39 UT, with upper limit up to 20.2 mag. The observations began at zenith distance = 46 deg. The sun altitude is -46.2 deg. The galactic latitude b = -46 deg., longitude l = 326 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2622469 We obtain a following upper limits.
