solar flare

"Some of the extreme ultraviolet light above active regions flickers erratically for a few hours before a solar flare," researcher Emily Mason said.

In a groundbreaking first, the Parker Solar Probe has successfully completed its closest encounter with the Sun. So where does this plucky probe go from here?

Parker Solar Probe is "venturing into a region of space that we never visited before," astrophysicist Nour Rawafi said.

"Even the most extreme solar events are part of the sun's natural repertoire," a researcher said.

The Aditya-L1 spacecraft is designed to watch the sun for any ejections of plasma that may hit Earth and damage power grids.

A G1 geomagnetic storm may hit tomorrow evening, with a G2 storm following in the early hours of November 29.

A sunspot named AR3901 that keeps flinging out M-class solar flares is about to face toward the Earth, putting us in the crosshairs for more flares.

An intense X2.3-class flare was released by the sun yesterday, followed by several M-class flares, which caused a series of radio blackouts around the world.

A November 6 solar flare hit X2.3-class in strength, causing Atlantic radio blackouts, with more potentially on the way if further solar flares are released.

The probe will orbit the sun "close enough to pass inside a solar eruption, like a surfer diving under a crashing ocean wave," NASA said.

"Sunspots are complex magnetic regions of the sun where energy can be stored in huge amounts," astronomer Peter T. Gallagher said.

A new sunspot named 3856 is facing Earth and has an unstable "beta-gamma-delta" magnetic field.

This stunning light show was triggered by a G4 geomagnetic storm caused by a plume of solar plasma ejected from the sun.

Star gazers can expect more glimpses of the northern lights as the sun reaches its solar maximum, causing more geomagnetic storms.

A "severe" solar storm is set to hit the Earth at any moment, with auroras visible across the U.S. tonight.

"The aurora may become visible over much of the northern half of the country, and maybe as far south as Alabama to northern California," NOAA predicted.

People across the U.S. caught a glimpse of the northern lights last night as a geomagnetic storm roiled in our atmosphere.

A coronal mass ejection from the sun is expected to trigger a G3 geomagnetic storm, causing the northern lights.

The X7.1-class flare is the second-most powerful this solar cycle—and an associated eruption could cause aurora in the coming days.

The Earth is prone to more geomagnetic storms during the spring and fall equinoxes than throughout the solstices.

Coronal mass ejection from the sun at the same time as a recent X4.5 solar flare is about to collide with the Earth.

The northern lights may light up the sky above states as far south as New York and Idaho thanks to a strange ejection from the sun.

August saw an average of 215.5 sunspots, the first time the average monthly sunspot number has been greater than 200 since September 2001.

"The aurora may become visible over some northern and upper Midwest states," the Space Weather Prediction Center said in a forecast.

The sun had 196.5 sunspots on average in July, the most seen in a single month since 2001.

"We are staring at the edge of scientific knowledge here. Whatever we find will be new," astronomer Mikko Tuomi told Newsweek.

"We're likely seeing the first traces of Cycle 26, which won't officially start until about 2030," researcher Rachel Howe said.

"There's just enough atomic oxygen at the top of Mars' atmosphere to appear the same color as green aurora on Earth," physicist Nick Schneider said.

Sunspot AR3738 is moving into a position that could send a proton storm raging toward the planet.

A polar cap absorption event was sparked after the sun released a solar flare from a sunspot on its opposite side to Earth.
