(Last updated 2013-04-03.)

I am mostly interested in making scientifically important observations, like timing occultations of or by Solar System bodies and measuring variable stars.

I am also interested in citizen science projects and participate in some of them, like Galaxy Zoo.

I have been an amateur astronomer since 1975 and worked at the European Space agency's (ESA) technical centre in Holland, ESTEC , on the ARISTOTELES mission, an earth gravity mapping mission.

Approximate coordinates: 55°20 N, 10°20 E

A similar question was posed on Stack Exchange site Mathematics: Teenager solves Newton dynamics problem - where is the paper?
