SN 2020fqv
2020 supernova event in the NGC 4568 spiral galaxy collision / From Wikipedia, the free encyclopedia
SN 2020fqv was a type II supernova which occurred in March 2020 in the spiral galaxy NGC 4568, approximately 60 million light years from Earth. The explosion was detected by both the Zwicky Transient Facility and the Transiting Exoplanet Survey Satellite. Observations were obtained by the Hubble Space Telescope both years before and just 26 hours after it exploded, as well as many other instruments, providing the first holistic view of such an event.[2][3][4][5][6]

The progenitor star is modelled to be a red supergiant with a radius of 800±100 R☉ and a mass of 15±3 M☉, fairly typical of type II supernova progenitors.[6]
