Hello Chris

If you want to observe a ToM (time of minimum/maximum) of a
brighter EB (eclipsinmg binary) star to make a time series, you
can take a look at e.g.:
With the EW typ stars (EB stars of type W UMa) you can start
at any time and measure a minimum within the next 5 hours
without having to use ephemeris before.

For a monthy list of brighter EB stars that require observations
take a look at:

What kind of photometry software do you own ?
