18 New Papers Link High Solar Activity To Medieval And Modern Warmth, Low Solar Activity To Little Ice Age Cooling

From No Tricks Zone, by Kenneth Richard

“It is generally accepted that the climate warms during periods of strong solar activity (e.g., the Medieval Warm Period) and cools during periods of low solar activity (e.g., the Little Ice Age).” 3,032 more words


'Massive Auroras' sighted around the Arctic Circle

G1-class geomagnetic storms are underway around the Arctic Circle on Oct. 16th as Earth enters a stream of very fast moving solar wind.

Veteran observers in Sweden are reporting one of the best displays in recent memory as “massive auroras” dance across the sky. 10 more words

What’s influencing our Sun?


Our Sun is a beautiful, bubbling mess of plasma that’s controlled by its magnetic field – and roughly once every 11 years, the polarity of that magnetic field is reversed, causing a spike in Sun spots and solar flares. 615 more words

Solar Topics - Where we're headed, SC25, and beyond

K9LA’s Amateur Radio Propagation host Carl Luetzelschwab gives a brief update on Solar Cycle 24, and then discusses the implication of the number of days with zero sunspots, the trend of the strength of the magnetic fields around sunspots, the correlation of the duration of solar minimum to the maximum of the next solar cycle, and several other issues. 26 more words


Chance of geomagnetic storms

A solar wind stream traveling ~550 km/s is expected to engulf Earth’s magnetic field during the late hours of Sept. 11th.

Its arrival could spark polar geomagnetic storms and high-latitude auroras on Sept. 9 more words
