In AAVSO Bulletin 78 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 2015 through February 2016 are presented here in list form (JD and Gregorian calendar dates) and in approximation of the main Bulletin table format.

Dear Observers,
AAVSO Bulletin 77 - Predicted Dates of Maxima and Minima of Long Period Variables for 2014 - is published in the new format that was introduced in 2011. The information that was included in earlier numbers of the Bulletin is included in this new format, along with more information. The Bulletin does not include stars that do not have an AAVSO mean curve.

In AAVSO Bulletin 77 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 2014 through February 2015 are presented here in list form (JD and Gregorian calendar dates) and in approximation of the main Bulletin table format.
AAVSO Bulletin 76 - Predicted Dates of Maxima and Minima of Long Period Variables for 2013 - has been published and is available from the AAVSO Bulletin page.
AAVSO Bulletin 76 gives predicted dates for 381 Mira and semiregular variables for the period January 2013 through February 2014. These dates are based on observations in the AAVSO International Database.
