There is a new 11th magnitude nova in Cepheus. Originally posted as a possible nova TCP J20542386+6017077, it has been confirmed spectroscopically to be a nova.
We have already created a sequence for it and you can plot charts using the name Nova Cep 2014 or TCP J20542386+6017077.
Happy hunting!

Hi Everyone,
As of about 9 hours ago N CEP 2014 was still right around discovery magnitude, my estimate being 11.68V at JD 726.998.
The new sequence stars that I looked at (115, 117, 120, 131, and 140) were VERY good ! A big thankyou to our chart/sequence maker(s).
good observing to all,
Steve
Details regarding Nova Cep 2014 (TCP J20542386+6017077) are in AAVSO Alert Notice 498. I also recommend looking at the light curve (use the AAVSO light curve generator) of this nova to date - even at just 3 days old, it's interesting!
Good observing,

A quick look with the spectrograph tonight at ~10A resolution shows a nice P Cygni H alpha line profile in a 10 min exposure
