eggen card project

AAVSO Eggen Card Project

Olin Eggen was an astronomer, a photometrist; he measured the brightness of stars. But being of the last generation, his data was not recorded on a computer. He used 3x5 index cards. Lots of them. The goal of this project is to make the data he recorded in the last century available to researchers today. 


This is an AAVSO project. It is managed by a volunteer, George Silvis (SGEO), and over seen by AAVSO HQ.

Communications about the project should be routed through the forum listed in the sidebar or directly to SGEO. Use this forum to discuss any problems with the portal, the project or whatever. Share tips on identifying stars too.
