(Last updated 2013-04-03.)

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 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. Interpreted "PGRE" as meaning "GRE Physics Test".

John Paul, do you mean GTO or GEO?

Was that based on a single microlensing event or several?

comment Are orbits interior to Jupiter's orbit less stable than orbits exterior to Jupiter's orbit?
Pluto's orbit was shown to be chaotic some years ago (not necessarily unstable). Does it mean Neptune's orbit is also chaotic?

comment Refraction and scattered light for NLCs
@Geoff Gaherty: the season started late this year. I saw some magnificent ones around 2011-07-10 and weak, but distinct ones, yesterday evening (2011-07-20T23:00Z+1) through thin clouds (only the Moon and the brightest stars were visible.)

comment What is so special about iron?
Actually, nickel-62 is the most tightly bound nucleus (per nucleon) followed by iron-58 and iron-56. Practicalities apply, though.

Can you move the first paragraph to a comment to Andrew's answer? This is not a forum.

+1. That is an outstanding answer.
