Have you seen this? I think it's a very interesting supernova, with magnitude 14.2 now (some days ago it was 14.8), and it very easy to see visually under dark skies, as if NGC 4125 had 2 nucleus. Is it posible to increase more the magnitude or it will be stable? It's said to be a type Ia supernova, located at roughly 70 millions LY distance. Its absolute magnitude is -17.5, and now it shines with the bright of 1.000.000 suns. Do you have more information?
