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).
