Insights into the physics of space weather that disrupts cell phones and creates Earthly havoc

From the American Physical Society News from the 2014 APS Division of Plasma Physics Meeting Each second, the sun hurls millions of tons of hot, charged plasma gas into space. This volatile “solar wind” buffets the magnetosphere, the magnetic field that surrounds the Earth, and can whip up geomagnetic storms that disrupt cell phone service,…

Partial solar eclipse shows off massive sunspot

From the National Science Foundation: Press Release 14-141 Spotlighting the sun October 24, 2014 Astronomers with the National Science Foundation (NSF)-funded National Optical Astronomy Observatory (NOAO) captured pictures not only of Thursday’s partial solar eclipse, but also of the “monster” sized active region or sun spot that has many comparing it to one of a…

Changes in Total Solar Irradiance

Total solar irradiance, also called “TSI”,  is the total amount of energy coming from the sun at all frequencies. It is measured in watts per square metre (W/m2). Lots of folks claim that the small ~ 11-year variations in TSI are amplified by some unspecified mechanism, and thus these small changes in TSI make an…

Sunspot-2192

Massive X class flare erupts from the sunspot 2192

As we previously mentioned on WUWT, the Sunspot 2192 which is as large as Jupiter had the potential of hurling large solar flares toward Earth. According to NASA’s spaceweather.com “Giant sunspot AR2192 has a ‘beta-gamma-delta’ magnetic field that harbors energy for strong explosions. NOAA forecasters estimate an 85% chance of M-class flares and a 45%…

Solar Update October 2014

Guest essay by David Archibald This essay provides a series of graphs that describe the current state of the sun in context with its history. Figure 1: Oulu Neutron Count 1964 – 2014 Cosmic rays are pushed away, to some extent, from the inner planets of the solar system by the Sun’s magnetic field carried…

Climate Dialogue about the sun

Guest blog by Marcel Crok Over at Climate Dialogue we have started a new discussion about the influence of the sun on the climate. People familiar with climate discussions know that the sun has been and still is a popular argument to explain at least part of the warming since 1750. This has to do…
