Erupting Sun May Have Sparked Cannibal CME Towards Earth
A recent solar event has led to the emergence of a "cannibal" coronal mass ejection (CME) that is expected to impact Earth, potentially triggering strong geomagnetic storms. Here are the key points:
Cannibal CME Definition: A "cannibal" CME occurs when a faster-moving solar plasma ejection overtakes and merges with a slower one, intensifying the resulting storm.
Recent Eruptions: The phenomenon was initiated by a powerful M9.8-class solar flare on November 29, followed by additional CMEs released on November 28.
Impact Timing: The combined CMEs are projected to reach Earth on December 1, leading to significant geomagnetic disturbances.
Storm Intensity: NOAA forecasts G3-level geomagnetic storms, which can disrupt satellite operations and radio communications.
Auroras Expected: The storm is likely to produce vibrant auroras visible at lower latitudes than usual, with potential sightings as far south as the continental U.S.
Historical Context: This event is reminiscent of past significant solar storms, such as the Carrington Event of 1859, although current impacts are expected to be less severe.
