AAVSO Alert Notices for Observing Campaigns and Discoveries

Note: This page, together with the AAVSO Target Tool Alerts/Campaigns target list, replaces the following AAVSO webpages: AAVSO Alert Notice Archive, AAVSO Special Notice Archive, and the original Observing Campaigns webpage. - July 2017

An AAVSO Alert Notice is issued irregularly in order:

  • to announce an observing campaign of short or long duration on one or more astronomical objects at the request of an astronomer or the AAVSO;
  • to announce the discovery of an object such as a nova or a bright supernova;
  • to report on noteworthy or unusual stellar behavior; or
  • to provide additional information as warranted about a campaign or an object announced in a previous Alert Notice.

Alert Notices are distributed electronically and are posted on the AAVSO webs

ite. Subscription to the Alert Notice is free.

The page below contains links to AAVSO Alert Notices, ordered by issue number with the most recent issue first. Links are also given to AAVSO Special Notices, which were issued when needed to provide supplemental information about an observing campaign or a discovery, or to provide information about other stellar activity. Observers should use the page below, along with information in the AAVSO Target Tool Alerts/Campaigns target list (button at right), to see what targets are in need of observations to support current observing campaigns and to help plan their observing schedules.

Note that a Special Notice is located under the Alert Notice with which it is associated. Special Notices that are not associated with events covered in Alert Notices are listed at the end of the year in which they were issued. Please note that, as of July 2017, AAVSO Special Notices are no longer being issued.

The format below is date (yyyymmdd), Alert or Special Notice number, Alert or Special Notice title/subject.  (Missing dates to be added.)
