MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB240624.81 (trigger No 740949590,16h 01m 57.60s , -07d 12m 36.0s, R=4.3) errorbox 106 sec after notice time and 140 sec after trigger time at 2024-06-24 19:22:05 UT, with upper limit up to 19.0 mag. The observations began at zenith distance = 49 deg. The sun altitude is -18.8 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB240624.81 errorbox 110 sec after notice time and 144 sec after trigger time at 2024-06-24 19:22:09 UT, with upper limit up to 19.1 mag. Observations started at twilight. The observations began at zenith distance = 50 deg. The sun altitude is -15.1 deg.
The galactic latitude b = 32 deg., longitude l = 4 deg.
