(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

Some copy editing (but there is still room for improvement).

comment How was this dot identified as a mystery planet originally (Pluto in this case)?
OK, this may not be too useful for the outer planets (Neptune is in retrograde motion 43% of the time), but couldn't the Earth's motion be compensated for?

Unless near opposition (retrograde motion), the rate of apparent movement is an indication of how far out it is, right?

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).
