[vsnet-alert 10751] Re: V723 Cas outburst? (fwd)

[Gary Poyner]

These are visual observations, not CCD.

The large amplitude of this 'old' Nova are surely caused by
it's P_orb!

This list is incomplete.  I have made 50+ observations in 2008,
all showing variations of 14.9-15.8 visual.

Best regards,
Gary
