AAVSO Times of Maxima and Minima of Long Period Variables: Current data

These data consist of formally published data for the years 1900 to 2008, and data for the years 2009 through the present for a subset of these stars.  Data from 2009 to the present were those used for calculations of the AAVSO Bulletin, and are considered preliminary.  For a description of this data set, please click here.

Stars with maxima and minima data are as follows:
