As I described on Friday, a type Ia supernova discovered Wednesday, August 24, in the nearby galaxy M101 in Ursa Major is the nearest type Ia supernova astronomers have found since 1972. The brightness of this exploding star is on the rise, and it could be visible in binoculars within a week or so.

Late on Friday, our good friend Anthony Ayiomamitis in Greece, a superb astroimager, sent his latest picture of the galaxy and its attendant supernova, which is reproduced here. Anthony shot six sample images of the field and estimated the supernova’s brightness at magnitude 13.3 on Friday evening. For full details on the image, see:
