(cba:news) OT 2102+02, and ASAS2243+08; also TT Ari and ES Cet (Joe Patterson) [2009-10-18T15:08:16Z]



Dear CBAers,

I saw this vsnet note, and thought we might jump to it. 2102+02 only permits brief runs in late October, but it's equatorial, so maybe we can stitch together good multi-longitude light curves. Greg, can you supply any other info on this star? 0.3 mag superhumps... whew, that sounds pretty interesting, and 2 hours could also be.

We're doing moderately well on ASAS2243+08, but it has started a rapid fade. Still a good target for up to a few nights.


OT J210205.7+025834: new SU UMa-type dwarf nova

   Greg Bolt has reported observations clearly showing 0.3-mag superhumps.
The period is around 2 hours.  Further observations are strongly encouraged
to determine the superhump period.

TT Ari campaign is going great... let's give this brazen star a long run in Oct-Nov 2009!

And oh, I forgot to mention ES Cet, now transiting near midnight, and available to everyone, though slightly favoring southerners. We've been tracking its 10-minute period, and I wanted to get one more solid season of timing it before publishing the Pdot or upper limit (it's an important constraint on the mass transfer rate, and hence evolution).
