Hi Joe,
Ok, I will keep CD Ind on my agenda and once in a while look it up.
BW Scl and VZ Scl could be covered (maybe even simultaneously).
You mentioned a recent paper. Is this already published or not yet submitted and the upcoming data could still be included?
I could try a 1 min on BW Scl for a couple of hours after the star does its meridian flip.
Regards,
Josch

Hi Josch, Robert et al,
OK, I bow to your judgment on this one. I've been marvelling at that
great data you've been sending... but 19.5, well, that seems to be just
a little too ambitious. Take an occasional peek to see if it comes back,
though; the light curves are quite beautiful at 17.5.
The ideal southern target now is BW Scl. We recently finished a paper
on this star... but right about now is the perfect time of year, and
with Josch's telescope we have the chance to get true 24-hour coverage.
At 16.6, the star's bright, and it almost always shows a sheaf of
interesting periods - including some strange ones: a superhump at Porb +
10%, and a 10-minute signal that might, or might not, be WD pulsation.
It has been oddly neglected over the years. It's sort of the southern
WZ Sge - but better, since it flashes a more complete set of periods.
Hmmm, maybe the southern V455 And would be a better comparison. Well,
no need to quibble - there are many fine stars up there!
VZ Scl is also promising, assuming it's in the bright state (15-16).
Only once did we carry out a few-day observation of it, which was
inconclusive. Other than the eclipses of course.

HI,
I see that Robert Rea did CD Ind last night. What is the present magnitude of this star? The last time I observed it it was below Mag 18.
Did it brighten again? Is it worthwhile to continue observations?
Regards,
Josch
