The AAVSO Bulletin: Predicted Dates of Maxima and Minima of Long Period Variables is a long-running publication of the AAVSO. It gives predictions of dates of maxima and minima for hundreds of long period variables (Miras and semiregulars) 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 2017 through February 2018 is Bulletin 80.
In 2011 the AAVSO Bulletin was 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. The Bulletin Generator, a dynamic form allowing the user to generate a customized Bulletin, was introduced in 2011 with Bulletin 74. It lets you 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. It also provides links for each star to the AAVSO Light Curve Generator, International Variable Star Index (VSX), and AAVSO maxima/minima values.
