Short summary
We provide detailed translations of some abnormal meteorological conditions in 43–33 BCE described in Chinese historical documents possibly related to the Okmok volcanic eruption in Alaska in early 43 BCE. The cold summer record and the abnormal color and low brightness of the sun point to the clear link to the volcanic impact. The reported duration for the visual condition of the sun to return to normal should be useful for researchers modeling the volcanic impact on climate.
