Just back from the SAS meeting, which was very solid, dazzling in spots.
It always leaves me with the feeling "We better raise our game to keep
market share!" Next June we (the CBA) would like to have a little side
meeting at the June AAS meeting in Boston - and hope this will draw some
European attendance. Only Enrique de Miguel (Huelva Spain) represented
the Euros this time around.
OT 2138+26 has done everything we'd hoped - it's really and truly a
large-amplitude nearby dwarf nova, likely of very long recurrence period
(close cousin to WZ Sagittae). Its location in Pegasus is no picnic in
May... but I really, really hope you guys can get maximally long light
curves, and I *really* hope for non-American coverage, so we can solve
the alias issues which otherwise might bedevil us. So far, Tom Krajci,
Bill Stein, and Gordon Myers have been holding down the fort. As Tom's
reports show, the superhumps are booming - so let 'er rip.
Earlier in the night, CR Boo, V893 Sco, and HP Lib remain attractive
targets. CR Boo is certainly in an odd state - it would be great to
have multi-longitude observations of it, so we can assess these long
ramps in light for which it is somewhat famous.
I'm actually still at Kitt Peak, trying to observe 19.5 mag white dwarfs
through clouds (and computers filled with mouse droppings). Not a good
combination. I get home late tomorrow, and leave everything to Helena
Uthas, who many of you met at Big Bear, and who will be postdocking in
CVs at Columbia starting December.
