I independently "discovered" this SN this morning. I looked at NGC 7793 and noticed two stars next to it. I knew that was unusual so I looked at Desktop Universe and saw the second star was not there. Then I looked at CBAT and found it had already been seen.
Back in the 1980s (7/8/83) I was looking at M77 and noticed a comet next to it. I thought I had discovered something but it turned out to be Comet Temple 2. Maybe the third time will be lucky.
The attached image from SkyMap Pro shows the galaxy without the SN. The star inside the green curve is mag 12.48, the SN is about 1' from it and the same magnitude.
