Tested Korean dim-Sun records as a volcano detector

Parsed the Goryeosa for every dim, red or lightless Sun and compared with the newest ice-core eruption list. Mostly spring dust; caught only the two biggest eruptions (1108 and Samalas 1257, with a 'blue Sun' in 1258). Then turned the idea toward the 1808 mystery: the later Joseon Royal Secretariat Diary records the weather every day, so a dim or red Sun in a Korean winter (no dust season) after December 1808 would support a volcano west of the Americas. Collecting that diary's daily weather for three winters.

How it connects

This step led us to Korean dim-Sun records track volcanic eruptions (Goryeo period, 918 to 1392)

This step is about Look west of the Americas for December 1808

This step led us to The Sun was blue and without light, then red like blood, Korea, early 1258

This step and then Read the Korean court weather diary for the 1808 eruption winter
