A couple of objects to take off the menu: RX2133+51 (until December,
when it's time for late-season pulse timings) and DQ Her (until Feb-Mar,
when it's time to start up the new season). These stars have been
getting great coverage from Tom, Enrique, Etienne Morelle, Jim Jones,
and Tut/George (I can't tell 'em apart since the data flows through George.
Here are two new ones:
V1432 Aql. We more or less concluded our season... BUT Suzaku (an X-ray
satellite) will be making a long observation in late October, and they
need timings of the eclipse (which should be easy) and the
not-quite-synchronous wave (harder, but multi-longitude should permit
it). That's our job.
CP Eri. We got some great data on this helium star in 1998 (oops)...
which we're now readying for publication. It's about 19.8 in
quiescence, so I don't expect anyone to salivate at that. However, its
eruption (to 16.5) frequency is unknown, and I suspect it erupts a lot.
When it erupts, drop everything you're doing, and follow it
tree-to-tree with time-series photometry. (and send to cba-news, -chat,
Goodyear blimp, etc.)
longer message tomorrow
