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!
