Hi CBAers,

I'm about finished with a paper on ES Ceti.  It's (arguably) just 
creeping back into the morning sky for southern observers - still way 
too early in the season for our usual many-hours time series.  However, 
since the binary period is only 10 minutes, you get a lot of bang for 
your buck with this star.  A few time series of one-hour duration would 
enable me to time the shallow "eclipses" accurately.  If you can 
accomplish that within the next month*, it would be great!

Two other short-period stars, well known to many CBAers and available to 
all hemispheres, are back in the morning sky: AO Psc and FO Aqr.  Both 
easy targets, and the subjects of (our) long-term timing studies later 
this year.  Good choices.


*Later would be good, too.  But I do want to send this paper off pretty
