(Last updated 2014-03-04.)

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.

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

comment Falling into Saturn or Jupiter, would we pass through it until we hit the nucleus?
@Andrew: I think he talks about having a headache and thus not being able to enjoy to go to heaven - in the first or second episode of the original radio series.
