(IAAC) Supernova 1999el in NGC 6951 brightening!
The following supernova should now be coming into visual range for
larger amateur instruments! Host NGC 6951 is just 5 degrees NE of
the bright star Alderamin in Cep, near the Wmost border of Dra...
It's a good-size (3') SAB spiral approx. mag 11 - not a hard find!
Clear skies,
