Ok, I got the facts better now (thanks to David Bishop, Bright Supernova Page) so a bit of an amendment to my previous stating 2013aa was the second brightest Supernova since 1987A.
Below are the maximum brightness that all the brighter ones since 1987A reached.
2013aa appears however to be the 2nd brightest at discovery and as an AAVSO member has now measured at 11.3 even allowing a give or take for all of them 2013aa still ranks in the top 5 in the last 26 years (1987A -today infact 26 years ago - thanks Astroron for reminding me) and within a whisker of being the 2nd. Still a remarkable find, congrats Stu!
So to all you visual observers, have you seen it yet or are Astroron and Malclocke on their lonesome?
2013aa in NGC5643 max brightness around 11.3 this time
2011fe in M101 max brightness around 9.9
2011dh in M51 max brightness around 11.1
2004dj in NGC2403 max brightness around 11.2
1998bu in M96 max brightness around 11.6
1993J in M81 max brightness around 11.3
