Newsletters

The VSS Newsletter is usually published four times a year. It provides project leaders with the opportunity to publish interim results and project information and for members to report on activities. It includes regular sections on publications, hardware and software relevant to variable star observers. You can filter the list by year by clicking on the links to the right.
