Spaceweather.com notified us that a white dwarf star had just gone supernova in the "Cigar" galaxy (M82, which is near the bowl of the Big Dipper). So I found it and here it is! The supernova star is the one inside the right hand part of the galaxy.
Here is a wider angle view of the area that also includes Bode's Galaxy (M81, below the Cigar Galaxy). You will also notice in the lower left hand corner a fuzzy patch of bluish light.That happens NOT to be a comet (as I erroneously stated in this photo) but another galaxy known as NGC 3077.
