Records kept by people living in Korea, China and Japan in 1770 have revealed evidence for the longest geomagnetic storm in recorded history<\/strong><\/p>\n

Almost 250 years ago, for over two weeks, the skies above parts of Asia lit up in what looked like a burst of fiery red. Those who saw the strange phenomenon kept notes of the event, and now it has been identified as potentially the longest geomagnetic storm ever recorded.<\/p>\n

A dim red sky reported to have been observed between the September 16 to 18, 1770 in East Asia was considered one of history\u2019s greatest geomagnetic storms. But now, new materials have come to light suggesting the storm lasted much longer, for nine nights, and covered an area twice as large as originally thought.<\/p>\n

A group of Japanese scientists led by Hisashi Hayakawa from Osaka University studied hundreds of historical records dating between September and October 1770, including government records and people\u2019s personal diaries. Using these records, they were able to piece together what happened during the event, and link this to sunspot drawings from the time.[…]<\/p>\n

Thanks for the tip, Mark–fascinating!<\/p>\n

Of course, I’ve read in-depth information about the Carrington Event<\/a>, but was completely unaware of the 1770 event.\u00a0 I’ve always said the biggest EMP threat will come from our local star. Frankly, it’s just a matter of time.\u00a0 I hope we’re ready!<\/p>\n","protected":false},"excerpt":{"rendered":"
