(Last updated 2014-08-23.)

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

revised How is the number of electrons in an atom found?
Copy edited (e.g. ref. <https://en.wiktionary.org/wiki/nucleus#Noun>)- but perhaps the meta information that is the first sentence should be removed. Added some context. (its = possessive, it's = "it is" or "it has". See for example <http://www.wikihow.com/Use-Its-and-It%27s>.)

comment Why is the sky of the moon always dark?
How reflective is the surface (for instance, in relative terms compared to a desert on Earth)?
