Very bright supernovae have been seen at the position of some of the nearest GRBs.

At the time, it was the second brightest supernova observed in the 20th century.

At apparent magnitude 13.8, it became the 3rd brightest supernova of 2009.

Although it is too dim to be seen by the naked eye, it is the brightest supernova visible to Northern Hemisphere observatories since 1937.

The event was similar to SN 2005ap, and other unusually bright supernova suggesting that it was a new type of supernova.

This eventually lead to the nebula being linked to a bright supernova seen in 1054 A.D. by the 1940s.

The last bright supernova from which neutrinos might have been detected occurred in 1604, more than three centuries before scientists even suspected neutrinos existed.

Very bright supernovae have been observed to accompany several of the nearest GRBs.

At apparent magnitude 12.5, it became the 2nd brightest supernova of 2008.

It is reported to be the brightest supernova yet recorded, twice as bright as the previous record holder, SN 2006gy.
