I just added the latest obs

I just added the latest obs as of this morning. It looks like the observing time (at least from the iTelescope SSO faciltity in Australia) is about another 3 weeks. So I'll image as long as I can. This object has decreased 1 mag V and 0.866 mag B between 9/11/2018 and 9/30/2018.

The original campaign (organized at his request) on this nova took place in 2018 (AAVSO Alert Notice 634).

Dr. Walter expresses his thanks to all observers who have contributed data, and asks for the observations please to continue!

Good observing,

Elizabeth
