    Yeah, clear everywhere in the southwest, it seems.  I'm observing a new 
    DQ Her star from Kitt Peak, since the CBA coverage of TT Ari is so good 
    - last night, "good" is a vast understatement.  I suppose the ideal is 
    to have 2 (or maybe 3, to indulge in a luxury) same-region observers on 
    it, to give room for error - equipment failure, sudden clouds, etc. 
    It's a pretty important night for TT Ari, with two more Galex windows 
    (430-500 and 610-640 UT).  But I'd love to have some help with the rapid 
    Last night was pretty much pure quiescent TT Ari, as most of you know. 
    I'll send out a spliced light curve to all of you in a couple of hours.
    Probably a good night for cba-chatter.  BTW Koji Mukai has secured 
    another 25 ksec of Swift X-ray time.  We have to get a *little* lucky, 
    but we hope to get part of this at pure quiescence, and part in one of 
    these flares.  Not yet scheduled, but probably will be in the next few days.
