(IAAC) supernova

Has anyone seen the supernova in NGC3877 recently. I saw it last
Saturday night. I almost missed the galaxy in a 10" reflector but the
supernova was distinct once I knew what I was looking at. I'm  wondering
if it continues to brighten or has leveled off. This is the first I've
heard of a supernova in another galaxy being visible in amateur scopes.
I saw somewhere that there is another one for amateurs in Sagitarius. Is
it common to be able to see supernova or is this something rare?
