Var Cas 06, He Liveth
(12 November 2006)

Dear CBAers,

Don't forget ol' Var Cas 06 = GSC 3656-1328 (w/3656-1399 as comp star).
We've been studying that star as an excellent candidate for microlensing
(ATel should be coming out tomorrow).  The event is not quite over yet, and
the rate of return to normal will be a significant constraint in judging
whether the microlensing interpretation holds up.  So follow that star!

I realize the apparently constant light level will not impress the
neighbors, or yourself either... but this is a sturdy investment!  V filter
would be nice, but we can definitely use unfiltered as well.

Tom, I've been putting all of the data on your instrumental delta-mag
scale, since you have the bulk of the data.  This means that your runs are
especially critical, since the delta-mags don't need any conversion.
I hope you can spare some more time for little VarCas!
