Anniversaries offer the opportunity to remember and reflect on the past, what has changed and what have we preserved or adopted long-term. The following anniversaries are intended to stimulate interest in Australian astronomical events that occurred 25 or more years ago in quarter century increments. Anniversaries can have different meanings for those who experienced them or for the consequences of the event. Not all are celebrations. If you would like to contribute please send the date and one line of text (similar to that below) to the HAAC secretary.
