And here's the news re CR Boo. Since it's out of season, I'm hoping for
very extensive multi-longitude cooperation on this one. New Zealand?
Perth? South Africa? I think the southerners are somewhat favored for
this despite the +8 degree dec - because of the mighty Sun, enemy of all
things western this month.
Not only is the superoutburst imminent, but the big superhumps are quite
short-lived. We're plenty interested in their aftermath (stretching
over a couple weeks)... but just what they do in that first glorious
day, that's been mighty elusive!

24 hours ago, CR Boo was in its low state at 17.3 mag. Right now
it's at 14.9 mag and it has risen ~0.35 mag since I started this run
(100 minutes ago). Considering that the next supermaximum was expected
at JD ~ 87, this looks like the rising stage to the next
superoutburst. As the brightness at supermax is ~14.1 mag, superhumps
will likely start to show up over the next few hours.
