AAVSO Bulletin 75 - Stars with Double Maxima
In AAVSO Bulletin 75 there are two stars that exhibit double maxima: 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 2012 through February 2013 are presented here in list form (JD and Gregorian calendar dates) and in approximation of the main Bulletin table format.
AAVSO BULLETIN 74 -Stars with Double Maxima
In Bulletin 74 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 2011 through February 2012 are presented here in list form (JD and Gregorian calendar dates) and in approximation of the main Bulletin table format.
AAVSO Bulletin 74 for 2011 - How to Use the Bulletin
AAVSO Bulletin 74 - Predicted Dates of Maxima and Minima of Long Period Variables for 2011 - is published in a new format. The information that was included in earlier numbers of the Bulletin is included in this new format, along with more information. This year the Bulletin does not include stars that do not have an AAVSO mean curve.

AAVSO Bulletin
The AAVSO Bulletin: Predicted Dates of Maxima and Minima of Long Period Variables was a long-running publication of the AAVSO. It gave predictions of dates of maxima and minima for hundreds of long period variables (Miras and semiregulars) in the AAVSO program, and was intended to be an observing guide and planning tool for all observers of LPV stars, amateur and professional alike.
