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
