MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB240430.81 (trigger No 736197684,13h 24m 04.80s , +01d 32m 24.0s, R=2.55) errorbox 198 sec after trigger time at 2024-04-30 19:24:38 UT, with upper limit up to 19.9 mag. The observations began at zenith distance = 44 deg. The sun altitude is -23.4 deg.
MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB240430.81 errorbox 1871 sec after trigger time at 2024-04-30 19:52:31 UT, with upper limit up to 19.4 mag. The observations began at zenith distance = 40 deg. The sun altitude is -49.2 deg.
The galactic latitude b = 63 deg., longitude l = 322 deg.
