A Month Without Sunspots

by Dr Tony Phillips, March 6, 2019 in SpaceWeatherArchive


March 1, 2019: There are 28 days in February. This year, all 28 of them were spotless. The sun had no sunspots for the entire month of Feb. 2019. This is how the solar disk looked every day:

How does this affect us on Earth? The biggest change may be cosmic rays. High energy particles from deep space penetrate the inner solar system with greater ease during periods of low solar activity. Indeed, NASA spacecraft and space weather balloons are detecting just such an increase in radiation. Cosmic rays can alter the flow of electricity through Earth’s atmosphere, trigger lightning, potentially alter cloud cover, and dose commercial air travelers with extra “rads on a plane.”

As February ended, March is beginning … with no sunspots. Welcome to Solar Minimum!

Munich Conference: Leading Danish Astrophysicist Says Solar Activity Has Significant Impact On Global Climate

by Prof. H. Svensmark, January 22, 2019 in NoTricksZone


Danish Professor Henrik Svensmark is a leading physicist of cosmic radiation. At the end of last year he made a presentation at the 12th International Climate Conference in Munich, where he demonstrated that the climate is indeed modulated in large part by cloud cover, which in turn is modulated by solar activity in combination with cosmic rays.

His theory is that cosmic rays, which are extremely fast-flying particles – which originate from dying supernovae – travel through the cosmos, strike the Earth’s atmosphere and have a major impact on cloud cover and thus climate on the Earth’s surface.

This, Svensmark says, has been confirmed in numerous laboratory experiments.
