(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 Two planets in same orbit - not planets?
Exoplanetary system KOI-730 was originally thought to have co-orbital planets (in an L4/L5 configuration).

comment The Pioneer anomaly finally explained?
Another quote: "Quantum vacuum fluctuations reveal themselves in the Casimir effect, the spaceship braking effect, the photon aging effect (red-shifting) and the atom orbital electron shaking effect. Quantum fluctuations affect all elementary particles, and, respectively, travelling through the fluctuating vacuum spaceships "shake" as if traveling on the uneven road, which results in their braking. "

comment The Pioneer anomaly finally explained?
Interesting theory. Quote from the article: "Anomalous braking was discovered for all space crafts, for which such calculations were technically possible. Moreover, there are facts confirming the braking of the asteroids as well.". Do you have a source for observational data documenting the braking of the asteroids?

comment Why is the measured distance to the Triangulum Galaxy much more uncertain than to the Andromeda Galaxy?
@Jus12: they are in the same region of the sky, on the order of 10 degrees apart.

comment What to show a beginner
M33 may be further away than the Andromeda galaxy (835 kpc ± 105 vs. 778 ± 17 kpc). "Under exceptionally good viewing conditions with no light pollution, the Triangulum Galaxy can be seen with the naked eye. It is one of the most distant permanent objects that can be viewed without the aid of a telescope.". Ref 1. Ref 2.
