A supernova was discovered yesterday in the Cigar Galaxy, M82 in Ursa Major. Mag 11.4 at the moment so should be visible in 4" scopes or bigger, but may get brighter. This is well up in the sky as soon as it gets dark and will be up there (behind the clouds!!!) all night.

Thanks to Rick for the heads up.  More info and a finder chart here -
