BeV35: GSC 703 1930
Comparison star was for all measurements GSC 703 2180 (12.2 mag),
which was checked to be constant.
Data analysis was made by Chris Lloyd, UK.
His comment:
GSC 703.1930 has a very strong series of frequencies at n.417
cycles/day.
Marginally the best is 0.41376 days (f=2.417), but the variation is very
sinusoidal and for most the error is very small, about 0.01 mag. It may
be a c-type RR Lyrae variable or perhaps an ellipsoidal variable.

Hallo Herr Moschner,
vielen Dank, dass Sie auch BeV36 beobachten möchten, folgend eine Auswertung
der bisherigen Beobachtungen von BeV35 durch Chris Lloyd.
Liebe Grüße,
Klaus Bernhard
Dear Mr Kiyota,
Thank you for your observations of BeV35. I have combined them them with
Klaus' observations and they suggest that the star is a very short period
variable, probably a delta Scuti or beta Cephei. The ephemeris of
maximum light is
JD_max = 2451603.071 + 0.15594xE
The period is probably correct, but not absolutely certain at the moment.
One more run from maximum to minimum should complete the light curve.
Regards Chris Lloyd

Firstly, thank you for the latest observations. I think the period is now
fairly well established, the main alias has I think been eliminated. The
latest ephemeris based on all the observations is
JD_max = 2451612.162 + 0.22632xE
and it looks like a beta Cephei variable. There are a couple of gaps in
the light curve but it is mostly covered. There is probably enough here
for (at least part of) an IBVS on this one.
