My guess is this is a supernova. If you look in the Single Exposures, it is visible in g-band exposures 229272 and 230044 (2013-09-01 and 2013-09-03), but not in later images.

If you look through the DR10 single exposures and include the ones we cut (Legacy Survey Sky Browser) then in the weight images you can see it in other bands taken in early 2013-09.

cheers,

Nice find. the transient Is unreported. not in the TNS, NED, SIMBAD. Too far south for PanSTARRS.

Cheers to you as well! Im gonna celebrate! I did look at the single exposures and saw its absence in some of the images which lead me to believe strongly supernova, but I thought this is too good to be true. And since ive been painting Novas I gotta put it on canvas!

This candidate is reportable - eg. it’s a scientific discovery, so we need your full name.

Joshua Adam Moore. Iowa City, Iowa. Found it 2 days after I turned 44. I would like to add. I would not have known about the survey without Anton Petrov’s show.

Since I made a “big mistake” on my first report, I had not been an expert in calculating.

What do you mean?

I overestimated the magnitude of the supernova. I used the flux measurement.

REDACTED: I know a few guys from the SN candidate hunt thread. Rick @Rick_N and Ine @Ine. I think they can report if they like.

Thank you for reporting this one. I had wondered about it as it was my very first one.
