I have been an amateur astronomer since the late 1970's. I enjoy observational astronomy, mathematics, and spaceflight. Cosmology and astrophysics are not as interesting to me.

In the past, I observed occultations (total and grazing lunar, asteroidal) and variable stars. Since my free time is limited now, I mostly enjoy watching satellites pass over.
