History of AAVSO Alert Notices and AAVSO Special Notices

Notifying observers and researchers of discoveries and requests for AAVSO observing assistance

Prior to the inception of the AAVSO Alert Notice in 1974, observers were alerted to a discovery or the need for observations of an object via a post card from AAVSO HQ or, if extremely urgent, a phone call from the Director or his/her assistant.
