First 'Swedish' supernova

A Swedish amateur astronomer has observed the first supernova seen from Sweden. Astrophysicists from Dark Cosmology Centre has obtained a spectrum of the supernova, showing that this is a rare type of supernova.

The new supernova, named 2006iv, is a rare type of supernova - a so-called type IIb (about 1 in a hundred supernovae). It is the explosion of a star more than 100 times as massive as our Sun. Type IIb supernovae are most likely originating from stars in a double star system.
