Charts and Sequences Updates

The AAVSO Sequence Team has been working hard for many years updating and improving charts and comparison star sequences. This page contains a list of the most recent updates as well as an archive of all the updates from the past and when they were made.

If you observe any of these objects please update your charts and photometry tables as necessary with the most recent version as soon as possible. Many of the lists are also available for download in CSV, XLSX, and PDF format.

Note: This Alert Notice was revised from its original text to correct a misinterpretation of the request from Dr. Echevarria, to update the recent observations, and to update the status of scheduled HST observations.  -  Elizabeth O. Waagen, 2 April 2020
