The light curve of R Scuti reveals a 71 day period between alternating deep and shallow minima, the deep minima taking place every 142 days. The behavior sometimes goes away, but inevitably returns. The Julian Date is a running count of days since January 1, 4713 BC, of the Julian Calendar. JD 2450000 corresponds to October 9, 1995.
