Yes, Jean Meeus has a worldwide reputation, it seems.
He's established a list of mutual planetary occultations in a span of 3,000 years (for instance Venus passing in front of Jupiter, or Mercury in front of Saturn, etc...none exist in our lifetime; the next one is 2065). I've asked him if I could put his list on the web, never got an answer; now, it's somewhere in my PC or in a iomega diskette, I don't remember.
He's sometimes putting comments on a bbs I've subscribed to. Once, I put "de planetarium" in a flemish post. He corrected me by saying planetarium is neutral, therefore it must be "het planetarium". I got vexed to see his only reaction to one of my posts was about a language mistake. Nevertheless, he's certainly well respected, here.
