AAVSO long-term light curves on variable stars contain crucial information that has a significant bearing on many outstanding questions in astrophysics. These light curves define the behavior pattern of variable stars and provide basic sets of observations that may be used to correlate spectroscopic, photometric, and polarimetric multiwavelength data, and to match theoretical stellar models.

The AAVSO Monograph format enables us to present long-term variable star behavior, with each monograph containing 20 or more years of computer-generated light curves on one star. Each Supplement to a Monograph continues the light curves of the same star, bringing them more up-to-date.

Monographs contain AAVSO observations of one star and cover many years. Print copies are also available through our online store. The cost for AAVSO members is $5, and for non-members is $10. Supplements are free if you are purchasing or already own the associated Monograph.

The print copies also include light curves in many intervals covering the entire period. You can plot the curves for any interval from 1963 on using our online light curve generator.
