Evidence the Sun may have turned “blue” during 1450s-1460s
A lecture by Dr. Willie Soon suggests that something odd was occurring with the view of the sun in the decades around 1450-1460, which he dubs the “Global Blue Sun” due to historical anecdotal evidence that has been recorded. The suggestion is that there was a massive volcanic eruption somewhere on Earth that put haze and ash into the air, turning the view of the sun “blue”.
