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.)
