These data are formally published for the years 1900 to 2008. For a description of this data set, please click here.
Note: A separate page exists for the data including unpublished times of maxima. Go here for the current data set including the most recent data (through February of the current year).
Long-term observations of long period variable stars are essential to the determination of period, change in period, change in behavior resulting from mass loss and/or evolution, mode of pulsation (fundamental or overtone), internal structure, and phase at specific times for these stars.
The AAVSO now distributes its published times-of-minimum data for eclipsing binary in single compressed files (.tgz and .zip), rather than as a searchable online index. For data on a specific star, unzip the compressed file, and search for the star's name among the included text files. These files contain updated publication information through November 30, 2005, the time at which the files were last updated.
