The recent GOLD neutrino alert IceCube-220205, GCN #31554, with an energy above 200 TeV is suggested to be associated with the blazar PKS 1741-03. We note that this is one of the brightest blazars on the radio sky and is one of only four blazars singled out by Plavin et al. (2020) as the most probable high energy neutrino sources. Original →
