MASTER-OAFA robotic telescope  (Global MASTER-Net http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy,vol. 2010, 30L)
located in Argentina (OAFA observatory of San Juan National University)
started inspect of IceCube 190331A error-box (Kopper et al. GCN24028, center RA,Dec=337.68deg, -20.70deg)
at 2019-04-01 09:04:32UT  (when error-box_altitude=12 deg, sun_alt=27 deg.)
with mlim=19.1 .

There is NGC 7293 (Helix Nebula) inside IC error-box with 10^4 yrs  age

Reduction will be continued.


MASTER Global Robotic Net received to socket IceCube alert 190331.29 with coordinates
RA,Dec=355.6349  +71.1170 (J2000) and error-box 8.9deg. http://master.sai.msu.ru/static/IC/IC190331.29.txt
and automatically inspected this localization by MASTER-Tunka, MASTER-Kislovodsk, MASTER-Tavrida
http://master.sai.msu.ru/static/IC/MASTERIC190331.29map.jpg with mlim 18-20mag.
If new coordinates from GCN 24028 by Kopper et al. were sent automatically to subscribers, IceCube could get follow-up in time.
