SOLAR WIND SPARKS BRIGHT AURORAS: A stream of solar wind hit Earth’s magnetic field on Sept. 4th, sparking some of the brightest auroras in years over parts of the USA. NOAA forecasters knew the solar wind was coming and correctly predicted the G2-class geomagnetic storm. However, the storm is lasting longer than expected and could persist through Sept. 5th.
