History of Sunspots
Could someone with some expertise take a look at this UNESCO Courier article, "The observation of sunspots - history of Chinese science", it seems the first observation of sunspots occurred earlier than 28 BC. -MrFizyx 15:23, 17 August 2006 (UTC)

Redundant and Questionable Data
I suspect this article could be further improved if someone were to fact check the unreferenced claims. Specifically, I think that the earliest record of meteor showers likely predates 687 AD by quite a lot -- the Perseids have been observed for around 2000 years, for example, and I found a website (http://www.essortment.com/all/meteorshowersl_rmmu.htm) that says the Lyrids were 1st observed in 15 BC! Also, 2 dates are given for earliest record of solar eclipse: Oct. 22, 2137 BC (surprisingly accurate!) and 776 BC; both can't be right.DoctorEric (talk) 17:47, 14 July 2010 (UTC)

Halley's Comet
"613 BC - In July, a Comet, possibly Comet Halley, is recorded in the Spring and Autumn Annals (秋七月，有星孛入于北斗)."

Halley's comet did not appear in 613BC Wikitrumpets (talk) 22:19, 8 October 2020 (UTC)
