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.

Update on V1280 Sco (N Sco 2007)

Dr. Fred Walter (Stony Brook University) posted an update in the Novae forum on the extremely interesting nova V1280 Sco (N Sco 2007). Here is the link to his post:

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,

Continue observations?


I have observed V1280 Sco for the past nearly 3 months every clear night. Observing season is ending and the star is at airmass 2.6 already. Should I continue observations as long as it is feasible or stop. Should observations be restarted as soon as the star is visible in the morning sky again at high airmass? I did so for V1047 Cen another interesting star (Fred Walter is also in the distribution list ).
