(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

comment What is the irregularity in Uranus' orbit that is caused by Neptune?
"to affect where they are orbiting around a particular spacecraft". Don't you mean "to affect where they are orbiting around a particular planet"?

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

Added some context. (its = possessive, it's = "it is" or "it has". See for example <http://www.wikihow.com/Use-its-and-it's>.) Removed follow-up question - they belong in comments to the question.

comment Does the Earth's rotation affect an object in the stratosphere?
I don't think removing the wind (presumably differential speed wrt. to the group below) from the equation is the same as removing the atmosphere (apparently whoosing by at 1256 km/h).
