Re: HD 189735

I caught this star in eclipse last night in Rc:

I also have a bunch of data in V from C. W. Robertson, including 
another primary minimum or two. I think we can refine the period on 
this pretty good now. Our baseline is 82 days. Once I have all of CW's 
data phased, we'll see how complete the V curve is.

Is everyone convinced that this is a short-period Algol (EA) like Dirk 
says? It seems very similar to RT And and MR Cyg from the Light Curves 
of Variables Stars book.

Cheers,
