(cba:news) v893 sco, V803 Cen, and the new dwarf nova (Joe Patterson) [2010-05-09T03:26:30Z]


Lotta new stuff in the sky! I hope that people will send in their OT2138+26 plans (as well as observations of course). It'll help me a lot; we're on the 1.3 m telescope, vast overkill of course for an 8th magnitude star... and I'd breathe a lot easier if I knew that the star was being well covered now by several USA (and subsequently NZ/AU) observers. Then we can go back to our little 20th magnitude white dwarfs.

Rod Stubbings alerts to two important events in the southern sky - a large brightening, possibly a superoutburst, in V893 Sco, the famous eclipser. And a low state in V803 Cen - also quite rare, as true for CR Boo. (These are both members of the very select class of pure helium CVs.) Both awfully well-placed in the May sky.

Not a good week for having conferences, when astronomers are exiled from their toys. You non-conference-goers out there, take up the challenge!
