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”.
I wonder if that blue sun was caused by an effect similar to that which causes the famous ‘blue flash’ seen at sunset in Key West and in other areas on the west coast of southern Florida? I’ve spent many an hour drinking sun-downers on the boat and in Tiki Bars waiting for just the right conditions to witness it.

What sheltered lives some people lead. And shonky educations.
Here’s a bombshell for them – Blue cattle:
And its got nice bouncy music (not exactly to my taste but hey ho)

It gets even worse. I used to tend/shepherd for my neighbour so-called Blue-Grey cattle
Comprising/being the offspring of a Galloway cow (black & hairy with short legs, friendly) cow and a White Shorthorn bull.
=Big. White. Passable legs. Horny
For gastronomes and folks who know what is good to eat (non rice eaters by example), the meat from Blue-Greys is considered to be the very best you’ll ever get. In Europe at least.
Comes about because the only grow really slowly.
In a nutshell – ‘blue’ is a shade of grey
And people familiar with firearms should know the colour – that of oiled/polished gun-metal
Not ‘blue’ blue at all.
In some Slavic languages ‘blond’ translates same as ‘blue’.
Here is an interesting essay on history and perception of blue colour

Just came to me that records in manuscript form of sightings of a blue sun would most likely be in Latin.
Latin colour names are rather indefinite .

What do the manuscripts say and what was the adjective? “Caeruleus” -perhaps which means blueish probably.

Most records would be manuscripts written in Latin. it was the preferred international language.
The colour names were indefinite, based on natural dyes
Caeruleus was blueish
Latin for “sky” is caelum. Blue is caeruleum or “sky blue”.

Re your 8 am post of 9-23-18:
You still miss the point of my post. You can have no PROOF that a solar minimum has ever occurred, since the same climatic effects that you cite would also occur in the presence of a large volcanic eruption (or eruptions).
You are probably familiar with the graph “Solar Irradiance, 1880-present” (or you can Google it).
It was compiled from proxy measurements (like those of the Little Ice Age), and shows, for example, a solar minima between 1983 and 1986, which coincides with the 1984-1985 La Nina (caused by the El Chicon eruptions of 3-29-82 (VEI4+) and 4-3-82 (VEI5).
It also shows a large solar maximum (again, for example) between 1985 and 1995, which coincides with the El Ninos of 1986-1988, 1991-1992, and 1994-1995, all of which were caused by reductions in atmospheric SO2 aerosol levels.
Thus, these changes attributed to changes in solar output, were instead caused by changes in atmospheric SO2 levels, which changed the magnitude of the proxy measurements.
These examples were selected because satellite TSI measurements are also available for the same time periods, and they show no corresponding changes in solar output.
In summary, there were multiple large volcanic eruptions during the Little Ice Age, and their SO2 aerosols HAD to have shown up in the climate record, no need for speculation that there were changes in solar output.
From late Pliocene times throughout our early Pleistocene Era from 2.6 mm years-before-present (YBP), Earth’s plate tectonic dispositions have driven periodic global Ice Ages averaging 102 kiloyears, interspersed with median 12,250-year interglacial epochs such as the Holocene from c. 14,400 YBP (BC 12,400).
On this basis, given the 1,500 year cometary/meteoritic Younger Dryas “cold shock” from 12,950 – 11,450 YBP, Earth’s Holocene Interglacial Epoch ended 12,250 + 3,500 -14,400 = AD 1350, coincident with Kamchatka’s super-volcano Kambalny Eruption precipitating a 500-year Little Ice Age (LIA) through 1850/1890.
As “amplitude compression” affects the 140-year LIA rebound to c. AD 2030 amidst a 70-year Grand Solar Minimum similar to that of 1645 – 1715, reducing cyclical fluctuations from 50 years (1939) to forty (1979), thirty (2009), and finally twenty (2029), odds are that any major astro-geophysical event will only aggravate a 668-year chill phase due to cover 80% of temperate-zone landmasses with glaciers over two miles thick for nigh 100,000 years.
“a 668-year chill phase due to cover 80% of temperate-zone landmasses with glaciers over two miles thick for nigh 100,000 years.”
Your statement is a bit ambiguous. Are you saying that after 668 years, there will be over two miles of ice? My (unreliable) mental math says that’s about 15 feet a year. Given New England has some 3 feet of water equivalent now per year, perhaps you meant that 668 years of March-like weather will trigger some 80,000 years of accumulating ice. Seems a bit unlikely without a lot of help.
Also, instead of “amplitude compression” did you mean “period compression? Your 50 to forty to thirty and finally twenty is shortening the period.
