(cba:news) Stars for February (Joe Patterson) [2013-02-08T22:26:08Z]


Hi Joe et al.,

I've been in South Africa at a nova conference, and it's a little hard to keep track of which stars are quite ripe right now. In the north, that is. In the south, it's a slam dunk: CP Pup and T Pyx (time to renew coverage of the latter now).

But two stars which are now desirable to observe at some length are BY Cam and "Paloma" (0524+42). Both are candidate or likely "asynchronous polars", and we'd like at least 1-2 more weeks to conclude coverage. ER UMa is also a good candidate, as Enrique said.

V1159 Ori is over. I'm not sure I said that before... but February is too late for Orion. It was an awfully good year!

Although we're mostly giving BK Lyn a rest this year (after last year's frency), we do want to peek in on it every so often to see when the supermaxima occur, and if possible measure one of the superhump periods. I notice that AAVSO data doesn't define either. So it appears that if we don't do this, no one will. It would be awfully nice if *someone* will decide to be the BK Lyn specialist. Pretty nice star to specialize in... and it would be unfortunate to lose track of cycle counts (for the supers) after investing all that energy in 2011-12!

The various DQs (intermediate polars)continue to be good targets for shorter observations.

Joe,

  BY Cam is definitely a good target for the first half of the night.

I would suggest you ER UMa for the second half. The superoutburst ended few days ago and it has just gone through the first normal outburst of the new supercycle.
We don't need a dense campaign on ER UMa, but just few runs to show (as I suspect) that is still showing negative superhumps. They should be definitely more
clearly visible now that is in its low state around 15.0-15.5 mag.

Mark,

I'm thinking of joining you on BY Cam. With our locations we wouldn't
overlap much and, when you're running again, be able to cover it for longer
time series.  Unless someone suggests a higher priority target in the next
few hours, I'll plan to do that tonight.

Thanks,
-Joe U.

Hi

I've been following BY Cam in the few clear nights we've had but the
weather
has been atrocious in the UK so it's not been easy.  Unfortunately a
technical problem will keep me out of action for a couple of weeks now.
It's an interesting target to follow so I'll carry on with it soon as I'm
up
and running again.
