And I just happened to catch it from my city light-polluted backyard, using a 5cm aperture SeestarS50!
Check it out ... on the left is my image (only 25 mins of data). The cross hairs indicate a 'new star' appearing in galaxy NGC 3621. The right image is from Stellarium and I have annotated where the new star appears, and how it was not there before.
This is a type II supernova, so a massive star's core collapsed and triggered off an extremely violent explosion that we are seeing 22 million years later.
It likely formed a neutron star or pulsar!
It is incredibly bright and I encourage everyone to turn their telescopes towards it and get data / light curves!
