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 GRB240420.19 (trigger No 735280430,17h 04m 21.60s , -27d 01m 12.0s, R=5.66) errorbox 61985 sec after notice time and 62023 sec after trigger time at 2024-04-20 21:47:28 UT, with upper limit up to 17.1 mag. The observations began at zenith distance = 71 deg. The sun altitude is -34.5 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB240420.19 errorbox 66581 sec after notice time and 66619 sec after trigger time at 2024-04-20 23:04:05 UT, with upper limit up to 16.8 mag. The observations began at zenith distance = 76 deg. The sun altitude is -31.1 deg.
The galactic latitude b = 8 deg., longitude l = 357 deg.
