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
Click here for Active Alert Notices.
There are two types of AAVSO Alert Notices:
- Observing Campaign
- 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 provide additional information about a campaign or the target of a previous Alert Notice
- Object of Interest
- to announce the discovery of an object such as a nova or a bright supernova;
- to report on noteworthy or unusual stellar behavior
An AAVSO Alert Notice for an observing campaign is issued as soon as a professional astronomer tells the AAVSO about a new, urgent need for special variable star observations, usually in connection with their research.
An AAVSO Alert Notice for an object of interest is issued in response to a discovery or other stellar activity that AAVSO HQ believes warrants in-depth coverage.
By subscribing* (free of charge) to the Alert Notices, you will receive them in your email inbox so that you can contribute crucial observations when they are most needed!
* To subscribe to the Alert Notices, log in to your AAVSO account (free), click "My account" at the top of the page, then click the "Profile" tab, then the "Email Settings" tab. Check the box next to "Alert Notices" and save your settings.
AAVSO Alert Notices are also posted on the AAVSO website.
Below are 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 (now discontinued) 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.)
For Alert Notices and associated Special Notices, jump to: Active, 2024, 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, 2014, 2013, 2012, 2011, 2010, 2009, 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 2000, 1999, 1998, 1997, 1996, 1995, 1994, 1993, 1992, 1991, PEP Alert Notices, un-numbered Alert Notices
For AAVSO Special Notices that are not associated with AAVSO Alert Notices, jump to SpNt2017, SpNt2016, SpNt2015, SpNt2014, SpNt2013, SpNt2012, SpNt2011, SpNt2010, SpNt2009, SpNt2008, SpNt2007, SpNt2006, SpNt2005.
ACTIVE before the date means that the observing campaign is active or that the target of an object of interest Alert Notice warrants continued coverage. All active Alert Notices for campaigns or objects of interest are grouped together below. When the campaign is concluded or the target no longer warrents coverage, the Alert Notice will be moved to the year in which it was issued.
The text in square brackets following the title of the Alert Notice refers to the AAVSO Observing Section under which the target falls.
