  1. New Member Summary October 1, 2007 - March 31, 2008 Annual (Adult): 50 Associate: 1 Sustaining: 2 Honorary: 1 (Tom Droege) ======================= Members from US: 34 Members from Canada: 6 Members from abroad: 14 (from 11 countries) ======================= Total New Members: 54

  2. In MemoriamMembers, Observers, Colleagues, and Friends of the AAVSO Tom Droege Batavia, IL Tom Droege spent 25 years as a Fermilab engineer and is best known for “Droege Supplies," orange NIM high-voltage power supplies in use all over the world. Droege built and operated several CCD-based telescopes from an observatory that he built onto his house. He founded The Amateur Sky Survey, an international collaboration organized to record and analyze images of the night sky using a technique he invented and incorporated into his telescopes. He received honorary lifetime membership in the AAVSO for his work on TASS. Walter R. Moos Koniz, Switzerland A devoted solar observer since 1997, Walter regularly contributed his sunspot observations to the AAVSO Solar Observing Program.

  3. William Douglas Hodgson (HWD) Chidlow, Australia A longtime observer and Sustaining member of the Association since 1988, Doug contributed ____ observations to the AAVSO. An engineer by trade, Doug was a member of the AAVSO infrared photometry group. He also donated his time as part of the comp star database working group. Doug dabbled in nova hunting, too, spending several years as a proud member of the UK Nova Patrol. Many AAVSOers had the pleasure of meeting Doug in 2002 at the 91st Spring Meeting in Hawaii.
