Thanks Palter, nice find!. ... a meteorite the size of a "wagonload" crashed into northern Greece sometime between 466 and 468 BC... Philosopher Daniel Graham and astronomer Eric Hintz of Brigham Young University in Provo, Utah, modelled the path that Halley's comet would have taken... The researchers show that Halley's comet would have been visible for a maximum of 82 days between 4 June and 25 August 466 BC... None of this proves the comet's identity, but Graham says such major comet sightings are rare, so Halley must be a "strong contender". Previously, the earliest known sighting of Halley was made by Chinese astronomers in 240 BC. To all -- please ping me to other topics which are appropriate for the GGG list.
