(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

Copy edited. (its = possessive, it's = "it is" or "it has". See for example <http://www.wikihow.com/Use-its-and-it's>.)

revised Can a human size object move so fast that it ceases to be observable?
Copy edited (but perhaps it should be MathJax'ed). Dressed the naked link.

revised Can a human size object move so fast that it ceases to be observable?
Copy edited (e.g. ref <https://en.wiktionary.org/wiki/let%27s#Contraction>) - but there is still room for improvement. Removed meta information (this belongs in comments).

Copy edited (e.g. ref. <https://en.wiktionary.org/wiki/everyday#Adjective> and <https://en.wiktionary.org/wiki/made_up#Verb>) - though more work on the last sentence is probably needed.
