[Aavso-photometry] VAR HER 04 - period & eclipses

[Aaron Price]

 Lew Cook (COO) has submitted a brief run on Var Her 04 last night with
some interesting data. A period of around 0.056 +/- 0.002 days is detected
with a semiamplitude of 0.028 +/- 0.004. Prominent eclipses are also
visible. A light curve of his data is at the URL below:

 Such a short period suggests this could be a member of the AM CVN class
of CVs with Helium secondaries. This is a rare class so could be a
significant find.

 Please observe this object as long as possible and with as high precision
as possible. Go unfiltered if you need to. I'll update the light curve as
more data comes in.
