Jan. 27th, Sillok recorded; “a shooting star appeared. Like an arrow with a fiery head, it was over ten feet long and grew to the size of a ridgepole [when viewed from the vantage point]. It arose from the west and headed northeast, falling in Jurchen territory. The whole area, above and below, was red all over. It became bright far and near, followed by thunderous sounds, which subsided in a moment, it is said.”
Sep. 23rd. Sillok Record:
On the nineteenth day of the eighth month, in the mi hour (1:30–2:30 pm), in the northwest part of the county, dark clouds suddenly covered an area encompassing a town and nearby fields stretching for about ten ri to its east. With deafening thunders, a shower of ice and hail bombarded the area for over four hours before stopping. The size of the formidable hail ranged from the egg of a goose to that of a duck and down to that of a chicken. They poured down simultaneously, destroying crops. Even birds and beasts, when hit, perished in great numbers. Hopes of harvest evaporated in a moment.
