NOAA has forecasted a "severe" geomagnetic storm to hit Earth this Friday, triggering aurora borealis. This storm comes as we approach solar maximum: the peak of solar activity during the sun's 11-year cycle. As a result, the National Oceanic and Atmospheric Administration issued a rare forecast for a "severe" G4 geomagnetic storm to hit Earth this Friday. NASADuring solar maximum, the sun develops more and larger sunspots, like the ones in region 3664, compared to quieter periods of solar activity. Severe geomagnetic storms like the one forecasted to hit this Friday are rare.

Read previewFor the first time in 20 years, NOAA has issued a G4 geomagnetic storm warning. NOAAAnd in the last 24 hours, AR3664 spit out four coronal mass ejections that are now hurtling toward Earth at roughly 560 miles per second, Owens told BI. Even states including Maryland, New York, and Pennsylvania, could catch a glimpse of the aurora low on the horizon, Young told BI. The reality is that we just won't know how bright, active, and wide-reaching the aurora will be until the coronal mass ejections reach Earth's atmosphere. The most extreme estimate of aurora and where they can be seen in the US came from Alex Young.

Read previewFor the first time in nearly 20 years, the National Oceanic and Atmospheric Administration has forecasted a "severe" G4 geomagnetic storm to hit this Friday, dazzling states across the northern US with aurora. G4 storms are the second-strongest type of geomagnetic storm. "If geomagnetic storms were hurricanes, 'severe' would be category 4," according to SpaceWeather.com. Solar storms happen when the sun shoots powerful explosions of highly-energized and magnetic plasma called coronal mass ejections toward Earth. Also, a severe storm might disrupt GPS, so it's best to have a written record and directions to important locations, like hospitals.

The sun has a big year in 2024, starting with a total solar eclipse across the US. NASA's Parker Solar Probe will fly closer to the sun than any spacecraft ever, almost landing on it. One of the main events this year will be a historically cool total solar eclipse crossing the US in April. AdvertisementIn a total solar eclipse, the moon passes in front of the sun as seen from Earth, darkening the sky. For example, NASA is launching three rockets during the April total solar eclipse, loaded with instruments to study how the sudden darkness changes our upper atmosphere.

CNN —On Saturday, a celestial spectacle will occur over North, Central and South America as an annular solar eclipse creates a “ring of fire” in the sky. The annular solar eclipse will begin in the United States at 9:13 a.m. PT (12:13 p.m. To view the annular eclipse safely, wear certified ISO 12312-2 compliant solar eclipse glasses or use a handheld solar viewer. Eclipse glasses allow for the safe viewing of all phases of an annular or partial solar eclipse. The small holes will reflect the sun’s crescent during a partial eclipse or a ring during the annular eclipse.

☆ The sun’s activity is peaking sooner than expected
▼ + stars: | 2023-07-14 | by ( Ashley Strickland | ) edition.cnn.com time to read: +11 min

Every 11 years or so, the sun experiences periods of low and high solar activity, which is associated with the amount of sunspots on its surface. Over the course of a solar cycle, the sun will transition from a calm to an intense and active period. During the peak of activity, called solar maximum, the sun’s magnetic poles flip. A solar activity spikeThe current solar cycle, known as Solar Cycle 25, has been full of activity, more so than expected. The solar storms generated by the sun can affect electric power grids, GPS and aviation, and satellites in low-Earth orbit.

CNN —A hybrid solar eclipse — the first of its kind in nearly 10 years — is on the way. The hybrid eclipse will begin at 10:37 p.m. What makes a hybrid eclipse uniqueOtherwise known as an annular-total eclipse, a hybrid eclipse is a function of Earth’s curvature and the event’s path. During full eclipse, at the very middle of the eclipse path, the antumbral shadow will create an annular eclipse for some and the umbral shadow will create a total eclipse for others. If you live in North, Central or South America, an annular solar eclipse will take place on October 14.

☆ Giant 'holes' dozens of times the size of our planet are appearing on the sun. Here's how they could affect Earth.

Two huge coronal holes, dozen of times the size of the Earth, have appeared on the sun. These coronal holes can spew solar winds at 1.8 million mph toward our planet, which can cause stunning auroras and disrupt satellites. Coronal holes aren't actually holes in the sunA coronal hole rotates across the face of the sun, streaming solar wind towards Earth, February 1, 2017. Coronal holes happen in the "corona," the atmosphere of the sun, and can only be seen in UV or X-ray light. We could see this month's coronal holes again next monthThe coronal hole came into view as the sun rotated.

That caused the Northern Lights, or aurora borealis, to make a rare appearance in skies across the US. The colorful lights were seen as far south as Arizona, much further than what was forecast. They normally occur in the Arctic, but powerful eruptions on the sun caused them to stretch as far south as Phoenix, Arizona before sunrise on Friday, according to images shared by photographers and skywatchers on social media. "Most people when they're seeing that far south... they're seeing it on the horizon," Young said. NWS La CrosseAnchorage, AlaskaAuroras in Anchorage, Alaska, on March 24, 2023.

☆ The Northern Lights could dazzle the skies from Washington to New York on Friday, blown by winds from a giant 'hole' on the sun

The Northern Lights could appear in the skies over some northern US states on Friday. The lights could be dazzling thanks to solar winds blowing from a giant coronal hole on the sun. NOAA/Space Weather Prediction CenterThese solar winds are coming from a giant coronal hole on the sun. As that giant hole spread across the corona, it blasted strong, high-speed solar winds into space, in the direction of Earth. They have previously driven the aurora lights as far south as New York and Idaho.

The sun is sporting a giant coronal hole that could fit 20-30 Earths across, back-to-back. Coronal holes blast rapid solar winds into space that travel 500-800 kilometers per second. Coronal holes are cooler in temperature, so they don't glow as bright and therefore look black against the rest of the sun. In this case, the solar winds from this coronal hole are scheduled to reach Earth by the end of this week. But coronal holes — even large ones like this — are far less violent.

☆ NASA to name solar scientist as agency's science chief, sources say

WASHINGTON, Feb 27 (Reuters) - NASA has picked a longtime solar scientist who heads its heliophysics division to become the U.S. space agency's science chief, according two people familiar with the decision. Nicola Fox, former top scientist on the Parker Solar Probe mission studying the sun, will be named this week as NASA's associate administrator for the agency's Science Mission Directorate, said the two sources, who spoke on condition of anonymity ahead of the official announcement. Fox will lead NASA's science directorate, a unit with an annual budget of roughly $7 billion that oversees some of the agency's best-known programs from the robotic hunts for past life on Mars to exploring distant galaxies with the James Webb Space Telescope. Fox will succeed Thomas Zurbuchen, a Swiss-American astrophysicist who had led the directorate since 2016 before his retirement in December. Sandra Connelly, formerly Zurbuchen's deputy, has been leading the directorate in an acting capacity.

☆ Fact Check-False claims about the sun and clouds at night shared online
▼ + stars: | 2023-01-18 | by ( Reuters Fact Check | ) www.reuters.com time to read: +5 min

Contrary to online claims, the earth is 93 million miles from the sun, is not flat and there is plenty of night-time footage of the planet taken from space, experts told Reuters. It also says the earth is flat and questions why clouds can’t be seen in nighttime images of the earth taken from space. Orsola de Marco, an astrophysicist at Macquarie University in Sydney, told Reuters that visibility of clouds at night could also depend on camera angle and the light source. Rather than a spacecraft looking directly through a cloud, shooting from an angle makes clouds more visible because more light can be reflected off the clouds, she said. Photos shared by the European Space Station at night showing clouds can be seen (here), (here), and (here).
