Impending Solar Eruption Threatens Earth with Auroras

A massive solar filament eruption on the sun has launched a coronal mass ejection (CME) towards Earth, prompting a G2-class moderate geomagnetic storm watch by the U.S. National Oceanic and Atmospheric Administration (NOAA) for September 19. If the CME arrives as expected, it could trigger a geomagnetic storm similar to the one on September 12, resulting in auroras and potential disruptions to HF radio communication and low-frequency navigation signals. Scientists anticipate more extreme space weather events as the sun approaches its peak in the 11-year solar activity cycle.
