Abstract

In this third paper covering the history of AAVSO charts I continue to describe not only the evolution of charts but the significant leap forward in all aspects of the chart production process that took place during the Henden Era, which started before Arne Henden became director and extends beyond his service as a Director of the AAVSO (2005–2015).
