MASTER-IAC robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB190417.46 ( 19h 33m 40.01s , - 0d 58m 59.88s, R=37.0167) errorbox 63754 sec after trigger time at 2019-04-18 04:50:53 UT, with upper limit up to 19.1 mag. The observations began at zenit distance = 41 deg. The sun altitude is -22.6 deg.
MASTER-OAFA robotic telescope located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB190417.46 errorbox 75579 sec after trigger time at 2019-04-18 08:07:57 UT, with upper limit up to 17.2 mag. The observations began at zenit distance = 44 deg. The sun altitude is -36.7 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.
