MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) was pointed to the EP241101a ( EP Team et al., GCN 38039) errorbox  48605 sec after notice time and 78664 sec after trigger time at 2024-11-02 21:43:53 UT, with upper limit up to  16.6 mag. The observations began at zenith distance = 55 deg. The sun  altitude  is -42.1 deg. 

The galactic latitude b = -34 deg., longitude l = 152 deg.


Real time updated cover map and OT discovered available here:
