Dear CBAers,
Well, the V1494 Aql campaign has been going very well, with some of the
usual suspects chipping in: Rea, Krajci, Starkey, MDM. Aside from a
little flickering, there's just the one period present, presumably
orbital. As Retter-Bos-Novak (from memory) mentioned a couple years ago,
the sharp component of this signal looks like a true eclipse. The period
from 2000-2003 is 0.1346667(2) d. The waveforms of the sharp eclipse and
of the slow variation change somewhat from year to year, and it will be
fascinating to follow this progressive change as the star gradually fades
back to quiescence.
It's a done deal. Wrapped up till next year. I will try to attach the
mean light curves from 2000, 2001, and 2003 (2002 is also in hand but is
somewhat corrupted). If they don't attach here, I'll put 'em in the next
message.
Good time to start the year's coverage on V1223 Sgr - and also on its
friends AO Psc and FO Aqr in the morning sky. Let's make it a good year
for DQ Her stars.
V603 Aql is still perched on the celestial equator, and everyone can get
good runs on it. It's really ideal for very long CBA runs, yet we've
never quite got them for some reason. It'll be around a while, but don't
forget it...
I hope to send another message tomorrow...
