The Sequence Team continues to be busy creating new sequences and updating old ones. The work we have done can be accessed by choosing either Observing at a Glance or Variable Star Charts under the Observing tab above the AAVSO banner. Or you can use this direct link: https://www.aavso.org/charts-and-sequences-updates-0
Please create new charts for variables you observe that have updated sequences. It's important that we all uae the same comparison stars.
The attached spreadsheet gives additional information about the variables with sequences that are completely new. It may help you decide whether a particular variable would be a good fit for your observing program. The spreadsheet includes a "number of observations" column. Note that a significant number of these variables currently have not been observed at all!
(Just added a file with additional details about new sequences for the 2nd half of 2019.)
