Currently it is somewhere around vmag 11, or so.

This is about as bright as our sun would appear from a distance of 400 light years.

This star is that bright from 12 million light years away, and it may be partially obscured by dust.

That is a hell of an explosion.

Awesome. Any estimates on the star's mass?

Presumably at or around the 1.4 solar mass Chandrasekhar limit.

It is believed to be (have been) an accreting white dwarf.

A carbon-oxygen white dwarf will accrete until its mass approaches the limit, at which point the core temperature reaches the ignition point for carbon fusion, the whole thing ignites and Boom. Either that, or if two merge, it goes over the limit, and the combined core collapses, with the same result.

Google for pics, it is predicted to increase in brightness for a week or two.
