As usual, the AAVSO Sequence Team has been working hard updating and improving charts and comparison star sequences. The following is a list of updates made during the first six months of 2019. If you observe any of these objects please update your charts and photometry tables with the most recent version as soon as possible. This list is also available for download in XLSX and PDF format (see the links at the bottom of this page.)
The charts and sequences team has been busy over the last several months creating new and updating existing variable star charts and sequences. The following is a list of updates made since 27 June, 2015. If you observe any of these objects please update your charts and photometry tables with the most recent version as soon as possible.
The following objects have new or revised sequences.
Improvements to existing sequences and creation of new sequences for newly discovered and previously known variables continues at a brisk pace. Below is a list of new or revised sequences adopted since April 4, 2013.
If you observe any of these stars, please be sure you are using th most recent version of the comparison star sequence on your charts.
This list is attached below in .csv and .xlsx formats for your convenience.
The following charts (listed in order by constellation) have new or revised sequences since December 20, 2012. This list is quite long. A .csv file is available as an attachment here at the bottom of the page as well.
If you observe any of these stars please update your charts as soon as possible.
The following charts (listed in order by constellation) have new or revised sequences since September 28, 2012. This list is quite long and includes all the stars in the new Binocular Program. A .csv file is available as an attachment here at the bottom of the page as well.
If you observe any of these stars please update your charts as soon as possible.
The latest release of APASS has allowed us to create new sequences and improve older sequences for hundreds of stars.
If you would like to request a new comparison star sequence for a star that currently does not have one please see the instructions for doing so located here.
If you find an error or have issues with an existing sequence, please submit those to CHET.
