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 GRB240324.08 (trigger No 732937833,02h 29m 16.08s , +14d 22m 58.8s, R=38.52) errorbox  831 sec after notice time and 866 sec after trigger time at 2024-03-24 02:04:54 UT, with upper limit up to  16.9 mag. The observations began at zenith distance = 79 deg. The sun  altitude  is -17.3 deg. 

The galactic latitude b = -42 deg., longitude l = 156 deg.
