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 GRB240827.34 (trigger No 746438824,13h 32m 24.00s , +27d 09m 00.0s, R=29.73) errorbox 14901 sec after notice time and 14932 sec after trigger time at 2024-08-27 12:15:52 UT, with upper limit up to 18.2 mag. Observations started at twilight. The observations began at zenith distance = 53 deg. The sun altitude is -16.4 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB240827.34 errorbox 43579 sec after notice time and 43610 sec after trigger time at 2024-08-27 20:13:50 UT, with upper limit up to 18.6 mag. The observations began at zenith distance = 67 deg. The sun altitude is -32.5 deg.
The galactic latitude b = 80 deg., longitude l = 34 deg.
