AAVSO Bulletin

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

The currently published Bulletin for January 2012 through February 2013 is Bulletin 75.

The AAVSO Bulletin has been significantly changed in its presentation and in the options available to the user. The fixed-format file has a very new look and contains more information than in the past. Completely new with Bulletin 74 is the Bulletin Generator, a dynamic form allowing the user to generate a customized Bulletin - choose your combination of stars, constellations, months, RA/Dec ranges, magnitude range - and choose an HTML table or a CSV file suitable for loading into a spreadsheet.
