2 In Memoriam Members, 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.

11 Robotic Observatories SRO –168 nights used out of 203 (83%) –2 nights lost due to mechanical failures –25235 images specifically for AAVSO ($0.02/image) –BVRI calibration of LPV, RR Lyr, cepheid, novae, GRB and other fields –Monitoring for Bill Dillon, Bart Staels, Jim Bedient –Personal research including novae monitoring

12 Sonoita Research Observatory 35cm robotic telescope Used 300 nights/year Southern Arizona USD$30,000+

13 Z UMi - a circumpolar RCB Real value of SRO is for long-term monitoring of many fields. Note near complete BVRI coverage (dropouts due to summer monsoon) of this circumpolar object. 15:02: :03:49

20 Schedule Purchase remaining components to automate dome, focus Install cloud camera, engineering data (labjack) Replace CCD camera Test (June?) Available to membership in Fall 2008

21 Cohen-Menke Observatory Lou Cohen donated his 12 LX200, ST8, Pro- Dome John Menke (retired owner of Technical Innovations) donated funds to refurbish system, volunteered to get system working Sending to Doc Clay for refurbishment Install somewhere at HQ for support, testing, robotic access

22 Lowell 24-inch Donated to AAVSO Need 40K to refurbish (submitting Mt. Cuba grant) Need site (negotiating with NMSU) Need to move it from exhibit hall soon

23 In Steele Visitors Center

24 Ellijay Observatory Tim Puckett has given us access to his 5 f/5.2 wide-field telescope Apogee U9000 (3kx3k) CCD camera, gives 3.2x3.2 degree FOV BVRI filters Fully robotic Will be used for all-sky calibration

25 Upcoming GUI interface for observing proposals Automated dispersal of images GUI for retrieval of FITS images Database of calibration photometry

26 Australia Trip March 2008 Goals –Arrange for distribution of Doug Hodgsons telescopes and AAVSO SSP-4 –Talk to amateur societies about citizen science –Meet with observatory directors about collaborations –Meet with AAVSO members

27 Distribution of Hodgson Equipment 12 LX200, ST4 guider, SSP3, etc. going to Deniliquin as public observatory (schools) 8 LX200, ETX125 going to ASWA to be given to young astronomers Books given to Perth Observatory library SSP-4 at Tom Richards house; to be loaned to another Australian amateur

37 Siding Springs 16-inch, 24-inch mothballed 40-inch soon to be mothballed 3.9m probably mothballed ~2012 UK Schmidt being used for RAVE, no plans after this Skymapper 1.3m (Bessell) under construction All funds channeled towards Gemini, GMT, space missions

38 Australia Notes Very active amateur scene, but not many people into variable stars NEED DIRECTION. No southern variable- star organization. Australia has been discovered. More educational groups, advanced northern deep sky enthusiasts, setting up robotic scopes Professionals involved in PLANET, microFUN followups when Bulge up (April-Sept); pretty open to collaboration otherwise Very little spectroscopic capability in Oz outside of AAO

39 Recent HQ News VSP released with Tycho/UCAC for bright fields (A-scale available) VSD updated with 22K reliable stars with photometry New standardized observing formats announced for both visual and CCD. Will be required in future; no ongoing support of vendor-specific formats Scion Journal issue shipped Several-session Futures meeting with staff

40 VSD/CompDB Currently proofing new photometry update - will release to community around April 25. Includes discrepant stars, new SRO calibrations, transforms from CMC14, 2MASS, UCAC and SDSS May 1 admin tool for ease of updating VSD June 1 revise photometry, some sequences, but then freeze VSD; send out chart CDs to organizations July 1 require use of new sequences and photometry VSP updates for batch download, fix bugs by June 1

41 Zapper Simplified version of internal AAVSO tool to inspect database observations Observers will soon be able to highlight bad observations for staff inspection, helping us validate Java based Note: observers do *not* change actual database


43 House Renovation Slow progress. Building permit not issued until January. NSTAR still has not connected electricity. Expected finish end of May Changes: separate utilities, raised ceiling 2nd floor, doubled rafters, extra insulation Current expenses $160K; expected total around $200K No showstoppers

44 Upcoming Campaigns May - HST/SDSS May, Dec - RS Pup June - eta Aur June - Supernova Special project: comparing vendor photometry
