A massive solar filament eruption on July 15 created a 'canyon of fire' on the Sun's surface, carving a deep scar over 250,000 miles long. The event also triggered a coronal mass ejection that is heading away from Earth, reducing potential space weather impacts. Astronomers continue to monitor the Sun for such activity due to its potential effects on Earth and space missions.
A massive "canyon of fire" was carved into the sun's southern hemisphere due to a large magnetic filament eruption. The eruption generated a canyon approximately 6,200 miles wide and 10 times as long. Solar filaments are arcs of electrified gas held above the sun's surface, which collapse when the magnetic field becomes unstable. Scientists are awaiting data to determine if the eruption resulted in a coronal mass ejection (CME) directed towards Earth, which could trigger impressive auroras. The current aurora season has already showcased dramatic displays and is expected to intensify as we approach the solar maximum.
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.
