(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

Some copy editing. Added some context.

revised Can the Big Rip really rip apart an atomic nucleus?
It is a proper noun, I think. Made the body more self-contained, etc.

revised What is the physics behind a soap bubble?
Copy edited (but the symbol for the wavelength of light seems to be missing). Interpreted "back" as meaning "black" (I think this is clear from the context, especially given away by the last sentence).
