☆ NOAA: Solar storm set to arrive, possibly creating auroras as well as affecting communications, GPS systems and power

The severe solar storm, classified as a level 4 on a scale from 1 to 5, also could disrupt communications, the power grid and satellite operations, according to officials at the center. “Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth’s surface,” according to the Space Weather Prediction Center. But if the storm escalates to a G5, auroras could be visible across southern states and elsewhere around the world. Before then, the last G5 storm to hit Earth was in 2003, resulting in power outages in Sweden and damaging power transformers in South Africa. The solar storm in May was the most successfully mitigated space weather storm in history, Dahl said.

☆ Sun releases the strongest flare in current cycle from the same region that triggered auroras this weekend
  + stars: | 2024-05-14 | by ( Kaila Nichols | ) edition.cnn.com   time to read: +2 min
CNN —After causing the dazzling waves of aurora borealis this weekend, our Sun isn’t done yet: The strongest solar flare of the current solar cycle occurred Tuesday afternoon, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center. That storm was the most extreme geomagnetic storm since 2003, the center said. Solar flares usually take place in active regions of the Sun that include the presence of strong magnetic fields. “The Sun’s activity waxes and wanes over an 11-year period known as the solar cycle,” the Solar Dynamics Observatory said on X. Researchers have been seeing more intense solar flares as we inch closer to the cycle’s end.

☆ NASA footage reveals 4 types of solar eruptions and 'holes' that could affect Earth as the sun grows more active

The sun is slamming Earth with solar flares and high-speed eruptions of plasma. Solar flares can have the power of 1 billion hydrogen bombsA solar flare erupts — the bright flash on the bottom right of the sun — on March 28, 2023. NASA’s Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash on the upper right – on March 3, 2023. CMEs are common culprits of solar storms on Earth, since they can send a powerful flood of solar particles washing over the planet. Coronal holes open a highway for solar windA video from NASA's Solar Dynamics Observatory shows the massive hole in the sun's atmosphere.
☆ Why the northern and southern lights appear to be so active right now

The northern and southern lights, which are usually confined to the Arctic and Antarctica, have generated awe and wonder for centuries. The northern lights were visible over St. Mary's lighthouse in Whitley Bay, England on Monday. The southern lights glowed over Lake Ellesmere on the outskirts of Christchurch, New Zealand on Monday. Over the next few years, the northern lights might appear further south more regularly, said Robert Massey, executive director at the Royal Astronomical Society. A National Weather Service employee took a photo of the northern lights in Maine on Sunday.
