Another nova in Cygnus was created by Keith g
According to CBAT's Unconfirmed Observations Page, a new possible
nova has been reported in Cyg (mag = 7.7C).
Coordinates are : RA 19H43M01.9S DEC +321913 (2000.0)
If the object was caught during the rise, it might become a naked-eye nova

Cheers Keith.
I've never actually seen one in the flesh as it were.
Lets hope indeed it brightens.

Cygnus gets all the fun in the past 20-odd years. For this one, does anyone know when it rises off the horizon at this time of year? At Cosmos, Cygnus was pretty low down at midnight as it was.

What would a supernova look like if i was to see one?
How would i know it was a nova if i saw it?
How do you detect them?
I mean they dont just appear overnight as a new bright light in the sky.

Be careful PJ, there are two different objects you're crossing your wires with!
A nova is when a star, mostly variable, increases suddenly in brightness for a period of time. This happens in stars that are approaching the end of their lives. Not to be confused with genuine variable stars which have a regular pattern of increase/decrease in brightness, either due to their type, or have a binary companion affecting/eclipsing them. The nova process is gradual, and the rise in brightness can take days. The majority of stars end in this way. The outer shell (seen as the 'nova') is expelled, and a heavy core becoming a white dwarf is what remains.
A supernova is when a (red) giant is at the end of its life cycle, has no useable fuel left (after going through the process of hydrogen fusion all the way up to iron), and has no other choice but to react violently, exploding. A supernova process is very quick, with almost no prequels to the event noticed.
Hope this helps,
