Monster solar storm that hit Earth discovered in the past

Something this big today would surely fry electrical grids, GPS, and communications. It may be bigger than the Carrington Solar event of 1859. Scientists have found evidence of a huge blast of radiation from the Sun that hit Earth more than 2,000 years ago. The result has important implications for the present, because solar storms…

Study: A Solar Signature in Many Climate Indices

Abstract Jean‐Louis Le MouëlFernand LopesVincent Courtillot We first apply singular spectrum analysis (SSA) to the international sunspot number (ISSN; 1849‐2015) and the count of polar faculae (PF; 1906‐2006). The SSA method finds 22, 11 and 5.5‐year components as the first eigenvectors of these solar activity proxies. We next apply SSA to the ten Madden‐Julian oscillation…

MSM finally gets that the sun's magnetic field has flipped

While we’ve known about this for quite some time at WUWT, going back to August 2013, the story is now starting to make the rounds in the MSM. And, NASA has created a cool visualization of the event. Video follows. From the NASA video description: This visualization shows the position of the sun’s magnetic fields…

Sunspot group AR1890 takes direct aim at earth

May produce a dangerous X-class flare that could directly impact Earth Steve Davidson writes: Right now, today, one of the largest sunspot groups of Cycle 24 – AR1890 – is pointing nearly strait at Earth. AR1890 has already produced a large X-class Level 3 solar flare Monday. from Spaceweather.com: X3-CLASS SOLAR FLARE: Earth-orbiting satellites have…

September doldrums – solar slump continues

While many science related government agencies are shut down (NASA GISS is deemed ‘non-essential’ for example) some remain open due to statements like this: Due to the Federal Government shutdown, NOAA.gov and most associated web sites are unavailable. However, because the information this site provides is necessary to protect life and property, it will be…

The Climate-Grain Production Relationship Quantified

Guest essay by David Archibald There is now consensus that the Sun has now entered a quiet period. The first paper from the solar physics community predicting the current quiet period was Schatten and Tobiska’s 2003 paper “Solar Activity Heading for a Maunder Minimum?”. To date, Solar Cycle 24 has shown similar maximum SSN amplitudes…
