The 2016 Spring Meeting in Review

The 105th spring meeting of the AAVSO was held at the Crowne Plaza in downtown St. Louis, Missouri, Thursday, May 4th to Saturday May 7th.  St. Louis was chosen due to it’s location in the middle of the continental United States. Council hoped this would encourage people to attend who don’t normally come to the fall meetings on the east coast. About a quarter of the attendees were first time attendees or people who don’t normally attend the fall meetings in Massachusetts.

Special Invitation to Regional Astronomy Clubs

The AAVSO cordially invites all members of astronomy clubs and astronomical societies in Indiana, Illinois, Ohio and Michigan to participate in our spring meeting, June 4-6, at Ball State University in Muncie, Indiana. We have something for everyone and opportunities for volunteers from the amateur community to receive complimentary registrations for your time and efforts.

Landolt Standards and 21st Century Photometry

Arlo Landolt should be familiar to most of the AAVSO community, not only as a friend and former councillor of the AAVSO, but as one of the leading figures of astronomical photometry and photometric calibrations.  Arlo Landolt's work on standard stars has set the standard -- very literally -- for astronomical photometry for nearly half a century.
