I began collecting data for this star on JD 2454402. I need to get the calculated times for P & S minima from that date forward. The only emphemeris I can even find this star on is the one located at http://www.as.ap.krakow.pl/ephem/. When I first began observing it, I did not record the calculated P & S minima times from the ephemeris because I really was not looking for any time differential.  But now that I appear to have detected an approx 30 minute differential, I would like to verify it. So, does anyone know where I might find past calculated minima for this star (or any others, for that matter)? I have contacted Gerry Smolyk, but he indicated that he had no data on this star.
