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 GRB240829.06 (trigger No 746587425,13h 38m 36.00s , +57d 16m 48.0s, R=1) errorbox 16 sec after notice time and 66973 sec after trigger time at 2024-08-29 19:59:54 UT, with upper limit up to 17.5 mag. The observations began at zenith distance = 62 deg. The sun altitude is -32.0 deg.
MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB240829.06 errorbox 167 sec after notice time and 67124 sec after trigger time at 2024-08-29 20:02:25 UT, with upper limit up to 17.0 mag. The observations began at zenith distance = 67 deg. The sun altitude is -35.6 deg.
The galactic latitude b = 59 deg., longitude l = 110 deg.
