h/t Roy W. Spencer March is a peak month for auroras, and this should be a good one in the coming days. A strong X-class solar flare lasting 5 hours…

SpaceWeather reports: One of the biggest sunspots in years has just rotated over the sun’s northeastern limb. AR3112 has a mixed-polarity magnetic field that harbors energy for strong X-class solar…

On May 23rd, 1967, a solar storm took place that was so powerful, it jammed radar and radio communications in polar regions and the US Air Force actually began to prepare aircraft for war thinking the nation’s surveillance...

Even though the responsible sunspot was located behind the edge of the sun, enough radiation reached our planet to cause a strong shortwave radio blackout.

Via SpaceWeather.com Earth-orbiting satellites have just detected an X1.3-class solar flare (March 30 @ 1737 UT). The source is active sunspot AR2975–the same sunspot that has already hurled at least two CMEs toward…

A secret behind the workings of sunquakes – seismic activity on the Sun during solar flares – might be hidden beneath the solar surface.

One of the biggest sunspots in years is emerging on the sun today. Hours ago it produced a C-class solar flare and a minor radio blackout over the Indian Ocean. This sunspot, if it holds itself together, will face Earth for...

In fact, it was this same time of year back in 1859 when a super solar storm - now known as the “Carrington Event” - took place during another weak solar cycle (#10)...

Using data from NASA's Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun's biggest flares from the last solar cycle, out of a set of nine.

from NASA Dec. 17, 2019 NASA’s Solar Dynamics Observatory has observed a magnetic explosion the likes of which have never been seen before. In the scorching upper reaches of the Sun’s atmosphere, a prominence — a large...

Guest post by Paul Dorian Overview The sun continues to be very quiet and it has been without sunspots this year 70% of the time as we approach what is likely to be one of the deepest solar minimums in a long, long time...

NOAA forecasters say there is a 55% to 60% chance of geomagnetic storms on May 15th and 16th when a series of coronal mass ejections (CMEs) could hit Earth’s magnetic field...

Sunspot AR2736, which hurled a Coronal Mass Ejection toward Earth yesterday, is growing larger and crackling with C-class solar flares. The active region now sprawls across more than 100,000 km of the solar disk and contains...

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...

By Jonathan Griffin A strong solar storm in 1972 caused widespread disturbances to satellites and spacecraft, and may have led to the detonation of mines during the Vietnam War, according to new research showing the event...
