Dear CBAers,
Just when the dwarf novae appeared to be settling down for a rest, along
comes a new one - Takamizawa V85, in which the Ouda people found deep
eclipses as well as probable superhumps. This makes it too interesting
to pass up! The deep eclipses enable accurate measurement of where the superping light
originates in the binary, a piece of information rarely available.
So let's go for this star. The position is RA=10 43 57.10, DEC=+58 07 33.3,
and it appears to be otherwise known as USNO1425.07642945.
At the same time, coverage of BY Cam by Cap'n Bob and Dave East has given
great promise, as you'll see from the light curve appended below. Fire
away on this star in the evening sky!
The best star for australites is definitely CN Ori. Marc Bos has been
observing it, and I hope you'll let me know of your observations (even if
unreduced) since then I'll try to arrange additional off-longitude
coverage, so we can properly decipher the period structure.
