Sergienko (Blagoveschensk Educational State University) MASTER Global Robotic Net ( http://observ.pereplet.ru, Lipunov et al.,2010,Advances in Astronomy, vol. 2010, 30L) will not observe IceCube-190819A (Santander et al. GCN 25402),so as error-box set faster then Sun and rised later then Sun in MASTER-Amur, MASTER-Tunka, MASTER-Kislovodsk, MASTER-Tavrida, MASTER-SAAO, MASTER-IAC, MASTER-OAFA. There is Sy1 PMN_J0948+0022 in current IC190819A error-box, that was also inside IC180908A (Blaufuss et al.GCN23214) error-box (in 5 degrees from IC190819A). http://observ.pereplet.ru/IC190819/Swift-PMN_J0948+0022.pdf In IceCube-190819A error-box there was Swift alert in 2017 https://gcn.gsfc.nasa.gov/other/764204.swift Also IceCube-190819A error-box includes * Sources from Fermi LAT catalog are in the list http://observ.pereplet.ru/IC190819/FermiLAT.html * QSO http://observ.pereplet.ru/IC190819/QSO.html * galaxies from GLADE cat. http://observ.pereplet.ru/IC190819/GLADE.html This message may be cited.
