Hi Alan,

Well this is the first time I’ve seen a plot of delta UMa myself.  VSX says the variability is of unspecified type, but this link suggests a possible EB    http://liber.onu.edu.ua/pdf/astro/all/OAP_9/000_pdf/bryukh.pdf

It’s quite interesting that the amplitude of the fades vary from one fade to the next.  Be nice to see a much longer plot.   My eyes are possibly seeing a secondary wave on that light curve.
