(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.

Applying the Maxwell–Boltzmann statistics to astrophysical objects Re: "Can the Universe be considered in thermal equilibria?". Why equilibria? Why isn't it equilibrium? |

Why is the universe so big? What is that indirect evidence? |

How long would it take to scan the visible universe for unique signals? More information about HUDF. |

What possible science could we do during the 2012 Venus transit? I observed the entire transit in 2004 using a 200 mm Cassegrain telescope with a mylar solar filter. I was lucky with the weather and was at the right latitude. The "black drop" effect was clearly visible both at ingress and egress. But it is a optical illusion (?). |

How do astronomers measure the distance to a star or other celestial object? Parallax is not the only direct distance measurement (although it is less universally applicable (no pun intended)). There is also the convergent method. |

Can any telescope be used for solar observing? @Anna Karenina: no, you need a narrow-band filter. A 1.5 Å filter will do for prominences. They are somewhat cheaper than a hydrogen-alpha filter proper. See for instance Solar Observing, section "Solar Prominence Filters". |

What tools do I need to track an orbit of a mystery object? How fast was it moving? For example, how long time, approximately, did it take to cross the field of view? 10 seconds, 1 minute, 5 minutes? |

Scientific value of timing total lunar occultations Interesting. What is the hit rate on asteroid occultations? Has the Hipparcos data increased it to something more acceptable than 10% in the 1980s? |

Questions about the Solar System This question belongs on Astronomy. Wait... It is not created yet (is in the commitment phase), but nearly everybody can help create it! |
