(Last updated 2018-08-28.)
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 have worked at the European Space agency's (ESA) technical centre in Holland, ESTEC, on the ARISTOTELES mission, an earth gravity mapping mission.
