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) was pointed to the INTEGRAL GRB240401.69 (trigger No 10651,05h 34m 06.25s , +22d 00m 11.5s, R=0.0546667) errorbox  946 sec after notice time and 961 sec after trigger time at 2024-04-01 16:54:58 UT, with upper limit up to  16.4 mag. Observations started at twilight.  The observations began at zenith distance = 36 deg. The sun  altitude  is -8.8 deg. 

The galactic latitude b = -5 deg., longitude l = 185 deg.


Real time updated cover map and OT discovered available here:
