MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB240721.08 (trigger No 743219692,11h 13m 28.08s , +53d 39m 00.0s, R=50) errorbox 39767 sec after notice time and 39807 sec after trigger time at 2024-07-21 12:58:14 UT, with upper limit up to 17.5 mag. Observations started at twilight. The observations began at zenith distance = 51 deg. The sun altitude is -11.3 deg.
MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB240721.08 errorbox 54458 sec after notice time and 54498 sec after trigger time at 2024-07-21 17:03:06 UT, with upper limit up to 18.5 mag. Observations started at twilight. The observations began at zenith distance = 56 deg. The sun altitude is -14.3 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB240721.08 errorbox 59480 sec after notice time and 59521 sec after trigger time at 2024-07-21 18:26:48 UT, with upper limit up to 17.7 mag. Observations started at twilight. The observations began at zenith distance = 54 deg. The sun altitude is -10.8 deg.
The galactic latitude b = 58 deg., longitude l = 150 deg.
