flare stars

The observers of the AAVSO are asked to participate in a long-term photometric monitoring campaign on a number of magnetically active dwarf stars, requested by Dr. Styliani (Stella) Kafka of the Department of Terrestrial Magnetism, Carnegie Institute of Washington.  She requests long-term monitoring of these targets with an observing frequency of one observation every three days taken with one or more filters.

Animations of Six UV Ceti (flare) stars

Multi-epoch animations for six UV Ceti (flare) stars. Because they are red dwarf stars, the known UV Ceti stars are confined to the immediate solar neighborhood. Many such stars have relatively large proper motions. Among the UV Ceti stars, WX UMa has the largest proper motion -- over five arcseconds per year. This means that charts for these stars must be updated occasionally to reflect their changing positions.
