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 EP241030a ( EP Team et al., GCN 37997) errorbox 33634 sec after trigger time at 2024-10-30 15:53:52 UT, with upper limit up to  18.1 mag. Observations started at twilight.  The observations began at zenith distance = 38 deg. The sun  altitude  is -14.6 deg. 

MASTER-Kislovodsk robotic telescope  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the EP241030a errorbox 47360 sec after trigger time at 2024-10-30 19:42:38 UT, with upper limit up to  19.4 mag. The observations began at zenith distance = 39 deg. The sun  altitude  is -57.2 deg. 

The galactic latitude b = 19 deg., longitude l = 118 deg.
