(probable) bright young supernova in M74 new
      #5992342 - 07/27/13 02:00 AM

A bright object has appeared near the galaxy M74, about two arcminutes SE of the galaxy's center. See

http://www.cbat.eps.harvard.edu/unconf/followups/J01364816+1545310.html

http://www.aavso.org/bright-transient-m74-psn-j013648161545310

The object was blue when I acquired CCD images around UT July 27 05:00, and maybe magnitude V = 13.

Because this galaxy is so close to the Milky Way, the supernova will likely become very bright -- perhaps close to V = 10 at peak. Please observe it, if you can, and report your results!

Took this image of the SN in M74 last night (7/31) with the Slooh remote observatory.

Based on the above image I'd estimate the PSN is about mag 12.7.

My observations in Rochester, NY, suggest that the SN has peaked in B and V, but it still rising a bit in I. See the light curve at

Took this image of PSN in M74 on the morning of 8/9. I'd estimate the SN is still about mag 12.5.

The SN is still 'bright' ! My image from Sunday night Sept 22 under a bright gibbous moon nearby - SN mag est unfiltered m13.7
