Sun news September 30: Happy perihelion, Parker Solar Probe!| EarthSky
Our active sun continues to disturb Earth’s geomagnetic field. At the time of this writing a G1 (minor) geomagnetic storm is ongoing. The threshold was reached at 9:15 UTC. We saw activity the whole time during our observation period between 11 UTC yesterday and 11 UTC today. Late yesterday and early today we saw another G1 disturbance, during the 0-3 UTC period. People have reported auroral displays in Europe, Canada and the U.S. The G1 storming occurred during the dark hours in the U.S. ...| EarthSky
Coronal mass ejection on February 27, 2000. A disk blocks out the light of the sun. The white circle indicates the sun’s surface. Learn more about coronal mass ejections here. Image via SOHO.What are coronal mass ejections?| EarthSky
This image shows a long filament of solar material, erupting into space. It happened on August 31, 2012. The accompanying coronal mass ejection (CME) traveled at over 900 miles per second (1,500 km/sec), rippling out into the solar system. Note: Earth to scale, but Earth is not this close to the sun. Image via NASA/ SDO spacecraft. A much-larger CME in the year 1859 caused the Carrington Event, which manifested as perplexing disruptions in the technologies then in use, such as the telegraph...| EarthSky
Scientists say it is now possible to predict the precise speed a coronal mass ejection (shown left in an artist’s impression) is traveling at and when it will smash into Earth (bottom right moving in our direction). And that’s even before it has fully erupted from the sun (top right). The new insights will help create more accurate space storm alerts for Earth.
