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.

Please note that if you haven't been checking these updates as they have been issued, you will also need to check the updates from previous months and years to see if there have been changes to your stars' sequences.
