(cba:news) [new WZ Sge-type DN in And] (Joe Patterson) [2008-09-02T21:46:18Z]



Dear CBAers,

Gracious! What a great object to spice up the new month and the new school year! I've been very busy with class preparation, and our electricity is about to disappear for a day or so. But I'll send a full CBA message when power comes back (tomorrow night)... and meanwhile, fire away on this lovely object with all available ammo. It has a good chance of being 2008's best performer... and with the very short period (77 min) it will give you lots of action each night. If you observe it tonight or tomorrow, send advice about comp star selection. There's some advantage in using the same comp star (though not a huge amount, since I always subtract the mean delta mag anyway). And unfiltered light is OK, as always, though there is some advantage in using a V filter while the star is adequately bright.

Happy observing!  It's great to see these WZ Sge's jump and say boo.

joe
