Ooops - still problems - you're not the only one moving too fast

The first article youn linked to had 690 BC, not 690 AD. (I like to use the more neutral BCE and CE for BC and AD.) It lists Halley at 684 CE (AD).

The second article gives a date of 690 CE (AD) for Halley's, but without citation - no idea where the information came from - it seems to be different than Chinese sources used in first series.
