AAVSO Bulletin 76 - Stars with Double Maxima

In AAVSO Bulletin 76 there are three stars that exhibit double maxima:  V Boo, R Cen, and R Nor. These stars therefore have primary and secondary maxima and minima. They are not included in the main Bulletin table. Their predicted dates of maximum and minimum for January 2013 through February 2014 are presented here in list form (JD and Gregorian calendar dates) and in approximation of the main Bulletin table format.
