OK, we've sent off our paper on V1674 Her. Pretty amazing target.
Co-authors should check their email/address/etc. I know a couple of
errors, but there might be more. We'll send off the proper paper
("proper" = for refereeing) in ~5-7 days.
V1674 will remain the highest priority in the next few months. But it's
around 17.1 now, and the raw light curves look pretty ugly since the
8-minute signal is of such high amplitude as to look like NOISE. I've
had no difficulty digging it out, and urge you to keep the faith for the
next few months.
But some other of our favorites have suffered at its hands, and let's
get back to them, too. Our of our common themes, large Porb changes in
CVs, needs attention... and in particular these stars:
These stars don't particularly need FREQUENT coverage, but you must have
LONG coverage - at least 3 hrs/night, and preferably 5 or more. The
reason is that we seek the *orbital* light curve. Those of you who have
been working V2487 Oph should keep that one going too, until Christian
and/or Maria calls you off.
I haven't said anything about U Sco here, because (a) I haven't studied
anything about this latest outburst, and (b) I've been assuming that
other people will do it. But so far, not much has appeared about its
light curve. Some of you probably know, though - could you share it?
