Two coronal holes on the sun are sending streams of solar wind toward Earth, prompting a G1 geomagnetic storm watch. While not unusual, geomagnetic storms can cause stunning auroras and disruptions to technology.
A massive coronal hole has formed in the sun's atmosphere, unleashing a powerful stream of solar wind toward Earth. Nearby, a second, slightly smaller coronal hole is also directing solar wind our way.especially at high latitudes this weekend. Recent solar activity has prompted the U.S. National Oceanic and Atmospheric Administration's ( NOAA ) Space Weather Prediction Center to issue a G1 geomagnetic storm watch.
While geomagnetic storm watches of this level are not uncommon, it's not something to ignore. A recent uptick in geomagnetic activity produced stunning northern lights displays that reached deep into. NOAA classifies geomagnetic storms using a G-scale, which ranks their intensity from G1 (minor) to G5 (extreme). The recent geomagnetic storm watch NOAA issued is rated as a G1.. These 'holes' appear dark because they are cooler than the surrounding material. Coronal holes allow solar wind to escape from the sun more readily, resulting in streams of relatively fast solar wind. Solar activity, much like Earth's weather, is unpredictable and difficult to forecast. Even though geomagnetic storm warnings at this level are not uncommon, they can occasionally amount to nothing. To stay updated on space weather and know the best times and places to catch auroras, consider using a space weather app tailored to your location. One app I recommend is'My Aurora Forecast & Alerts,' available on both
