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) was pointed to the Swift GRB240829.16 (trigger No 1251252,09h 32m 14.16s , -18d 43m 40.8s, R=0.05) errorbox 24 sec after notice time and 46 sec after trigger time at 2024-08-29 03:57:14 UT, with upper limit up to 15.6 mag. Observations started at twilight. The observations began at zenith distance = 76 deg. The sun altitude is -13.9 deg.
The galactic latitude b = 24 deg., longitude l = 251 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2580148
We obtain a following upper limits.
Tmid-T0 | Site |Filt.| Expt. | Limit| Comment _________|_____________________|_____|_______|______|________
52 | MASTER-SAAO | P/ | 10 | 15.4 | 69 | MASTER-SAAO | P/ | 10 | 15.6 |
The observation and reduction will continue. The message may be cited.
