AAVSO Observer Code
American Association of Variable Star Observers (AAVSO)
Albuquerque, NM, US
I have been an amateur astronomer off and on since the late 1960s when I was a youngster. I joined AAVSO in the early 70s, but let my membership lapse after entering college (just too many other things to do). I earned a bachelor's degree in astronomy/physics in 1977, then went on to graduate school to study optical physics in the early 1980s. I worked professionally in several physics disciplines after that, but my interest in astronomy (amateur and professional) returned in the early 90s, though it was not my primary job. I was pleased to be able to do some computational astrophysics in the modeling of pulsating variable stars while I was at Los Alamos National Lab. I rejoined AAVSO at that time, and have been a member ever since. After Los Alamos I worked for three major observatories as a telescope operator and instrumentation specialist. These days I am retired but I occasionally get out into my back yard and dark sky locations to do some variable star observing. I also do some collaborative work in computational modeling of pulsating variables with colleagues at Los Alamos. My interest as an amateur now is observing DCEP, W Vir, RR Lyrae, and SRD variables. I am also trying my hand at light curve data analysis.
