More on the "old nova" project...
Enrique has obtained a week of coverage on V Per. At 18.5, it's a very
challenging target. Still, some USA observers could handle it, and that
would provide the longitude span that enables us to do sensitive period
search. For the next 1-3 weeks, it's a very good target for the
ambitious. I can see now that the orbital period is stable, which was
my #1 question, but the other questions - superhumps, orbital waves, and
past periods - are still up in the air.
DN Gem and DM Gem are 16th magnitude old novae that are inadequately
studied. Red meat for us! - especially DN since its orbital period is
"known" to be pretty short (3 hours).
And in the south, HZ Pup and T Pyx are good choices, having finally
poked out from behind the Sun.
