AAVSO Bulletin 78 - Predicted Dates of Maxima and Minima of Long Period Variables for 2015 - 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 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.
The pulsating red supergiant Antares (“anti-Mars”), at V = 1.06, is the 15th-brightest star in the night sky, but it gets less attention than its near-twin Betelgeuse. Check the length of their entries in wikipedia, for instance.
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.
