(cba:news) september stars: v466 And, DV Sco, BW Scl (Joe Patterson) [2008-09-08T02:04:23Z]


Dear CBAers,

As most of you know, OT0200+44 has been renamed V466 And... and is likely in the midst of a long, bright outburst - the first ever seen in this star. The powerful "common superhumps" have apparently not yet appeared, but are probably just a day or two away. This is a great, great target - make every effort to get long time series for the next couple of weeks!

This is by far the top priority object - best to spend all night on it.
If horizon problems preclude evening coverage, SDSS2333+15 (Peg) and GD 552 (Cep1) are good alternatives.

In the southern hemisphere, Berto has been obtaining steady coverage of DV Sco (early evening) and BW Scl (rest of night). These have been extremely rewarding - DV Sco is a flashy new superhumper of exceptionally long period, and BW Scl is flashing strong orbital and pulsation signals. The latter are the strongest and simplest we have ever seen - simple enough that we'll be able to count pulsation cycles from night to night, and thus measure periods very accurately.

A simple menu. Sorry, no bright stars in the first tier. If you need 'em, AO Psc and V592 Cas are pretty good choices.

Clear skies!
