AAVSO Special Notice

Special Notices include announcements on interesting and/or rare stellar activity that do not involve new coordinated campaigns or may not rise the level of importance of an Alert Notice. The goal is for the Special Notie to be quick and brief. Should the announcement warrant further attention, it may be followed by an Alert Notice.
