AB  - AT2021afpi was a 10 mag outburst seen by the MASTER-Tavrida autodetection system in temporal coincidence with the astrophysical neutrino candidate IC211125A. The object was observed as an optical bright transient, initially classified as a classical nova. Follow-up observations by the VERITAS instrument at gamma-ray energies > 100 GeV on the nova location resulted in no detection for an exposure of 5.5 hours. Further spectroscopic reports reclassified AT2021afpi as a dwarf nova of the type WZ Sge-Type, which are not expected to be neutrino emitters. A possible blazar detected by Fermi-LAT, 4FGL J0248.0+2232, which lies within the 90
