The northern lights may be visible in several northern U.S. states on Wednesday due to geomagnetic storms caused by solar winds and a coronal mass ejection, with brighter and more widespread displays possible as a result.
A CME has arrived and is passing over Earth, causing geomagnetic storms mostly in G1-G3 levels, with a G4 storm still possible tonight, leading to minor disruptions in HF radio and navigation signals.
Space weather forecasters warn of severe solar storms caused by recent coronal mass ejections from the sun, which could produce vibrant northern lights visible across much of the northern U.S. and disrupt communications, GPS, and power grids. The sun is currently at the peak of its 11-year activity cycle, increasing aurora activity and space weather events, with experts advising caution and preparation for potential disruptions.
Space weather forecasters warn of severe solar storms caused by recent coronal mass ejections from the sun, which could produce spectacular auroras visible across much of the northern U.S. and even further south, while also potentially disrupting communications and power grids. The sun's heightened activity, part of its 11-year cycle, increases the likelihood of these displays and disruptions, with experts advising on how to view the auroras safely and effectively.
Astronomers are monitoring a large sunspot cluster, Region 4274, which has produced multiple powerful solar flares, including X-class events, potentially impacting Earth's communications and power systems as the sun approaches its active peak in its 11-year cycle.
The northern lights may be visible in northern U.S. states due to minor geomagnetic storms caused by a coronal hole on the Sun, with the best viewing times between 10 p.m. and 2 a.m. and visibility extending to parts of Washington, Idaho, Montana, North Dakota, Minnesota, Wisconsin, Michigan, Maine, and Alaska.
The NOAA forecasts a higher chance of visible northern lights in 15 U.S. states due to geomagnetic storms caused by solar coronal mass ejections, with the best viewing times between 10 p.m. and 2 a.m. and potential impacts on radio communications.
The northern lights may be visible from several U.S. states along the U.S.-Canadian border tonight due to minor geomagnetic storms caused by solar winds from coronal holes on the Sun, with the best viewing conditions being northward and around midnight.
Scientists warn that solar 'space tornadoes' can trigger geomagnetic storms causing global internet outages, costing billions, and propose deploying a constellation of solar sail-powered probes for faster space weather detection to mitigate these risks.
Forecasters at NOAA predict a moderate chance of seeing the Northern Lights in northern U.S. states and Alaska on Tuesday evening due to minor geomagnetic storms caused by solar activity, with the best viewing times between 10 p.m. and 2 a.m. Travelers should head north and away from city lights for the best experience, and photographers are advised to use tripods and wide-angle lenses.
Astronomers warn that current space weather detection systems are insufficient to predict solar events like coronal mass ejections, which can disrupt Earth's technology. They propose a new constellation of satellites called SWIFT to improve monitoring and warning capabilities, especially during the Sun's active solar maximum period.
The upcoming period around the fall equinox could see a brief but spectacular increase in Northern Lights displays due to the Russell-McPherron Effect, which causes more intense geomagnetic storms when Earth's magnetic field aligns with the solar wind, especially during the sun's peak activity cycle.
A geomagnetic storm caused by a recent solar eruption may allow over a dozen U.S. states, including parts of the Midwest and Northeast, to see the Northern Lights on Labor Day, with the best viewing conditions between 10 p.m. and 2 a.m. from high vantage points away from light pollution.
A new study warns that rising CO2 levels are cooling Earth's upper atmosphere, which could lead to sharper increases in atmospheric density during geomagnetic storms, potentially causing more satellite drag, shorter satellite lifespans, and disruptions to communication and navigation systems.
A new study reveals that space hurricanes, electromagnetic plasma storms over Earth's poles, can occur during calm space weather conditions and mimic the effects of geomagnetic storms, disrupting GPS and satellite signals without solar activity, highlighting the need for better detection of these stealthy phenomena.
