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…

Declining Solar Activity

BOB HOYE In the 1990s, solar physicists, Penn and Livingston, called for a long decline in solar activity. This is the case and it is nice to see such work confirmed by events. Solar Cycles # 23 and 24 are the weakest since the early 1900s. The current run of consecutive Spotless Days is out…

Amid the dimmest Sun since 1978 – a month without sunspots

The sun today is cue-ball blank, a perfect unmarred sphere: The sun has just passed an entire calendar month with no sunspots. The last time this happened, in August 2008, the sun was in the nadir of a century-class Solar Minimum. The current stretch of blank suns shows that Solar Minimum has returned, and it…

Sunspots: Labitzke Meets Bonferroni

Guest Post by Willis Eschenbach In a previous thread here on WUWT, a commenter said that the sunspot-related variations in solar output were shown by Labitzke et al. to affect the stratospheric temperature over the North Pole, viz: Karin Labitzke cracked that nut. She was the first one to find a correlation between not one…

Weak Solar Cycle: Cosmic rays increase 4th year in a row

Increased exposure for airline travelers at high altitudes. New data released by the Earth to Sky Calculus/Spaceweather.com high-altitude ballooning program show that atmospheric cosmic rays are intensifying for the 4th year in a row–an ironic side-effect of the decaying solar cycle. The new results are of interest to everyone from astronauts to air travelers. This…

Evidence for a new fundamental constant of the sun

From NORTHUMBRIA UNIVERSITY and the “solar constant” department New research undertaken at Northumbria University, Newcastle shows that the Sun’s magnetic waves behave differently than currently believed. Their findings have been reported in the latest edition of the prominent journal, Nature Astronomy. After examining data gathered over a 10-year period, the team from Northumbria’s Department of Mathematics, Physics…

Spotless Sun Sparks a Geomagnetic Storm

Right now, solar Minimum is in full swing. As you can see, the sun is completely spotless. But, last night the spotless sun produced a G1-class geomagnetic storm with bright auroras reported from Iceland to Alaska.  More lights are in the offing as a stream of solar wind is expected to buffet Earth’s magnetic field…
