MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 240329A ( Fermi GBM team, GCN 35993) errorbox 567 sec after notice time and 601 sec after trigger time at 2024-03-29 21:53:08 UT, with upper limit up to 16.5 mag. The observations began at zenith distance = 81 deg. The sun altitude is -59.4 deg.
The galactic latitude b = 18 deg., longitude l = 18 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2410319
We obtain a following upper limits.
Tmid-T0 | Date Time | Site | Coord (J2000) |Filt.| Expt. | Limit| Comment _________|_____________________|_____________________|____________________________________|_____|_______|_______|________
