A rare 'cannibal' coronal mass ejection (CME) from sunspot 4455 is set to impact Earth today, potentially causing auroras visible in 23 U.S. states. This event follows a series of powerful solar flares and is part of an ongoing solar maximum phase, which may lead to more extreme space weather.
- 01The CME originates from sunspot 4455, which is classified as an 'anti-Hale' sunspot due to its reversed magnetic polarity.
- 02This event is expected to create a strong (G3) or possibly severe (G4) geomagnetic storm upon impact with Earth.
- 03Auroras may be visible as far south as states including Oregon, Nebraska, and Pennsylvania, in addition to northern states.
- 04The current solar activity is part of the sun's 11-year cycle, with a peak in sunspot production expected in 2024.
- 05Historical references include the 1859 Carrington Event, which was a massive solar storm that caused widespread disruption.

Tonight, a 'cannibal' coronal mass ejection (CME) from sunspot 4455 is projected to strike Earth, likely resulting in auroras visible across 23 U.S. states. This CME, which began on June 2, is the result of a series of powerful X-class solar flares and represents a significant solar event. The combined CME is anticipated to generate a strong (G3) or even severe (G4) geomagnetic storm, affecting the Earth's magnetic field and enhancing auroral displays. States such as Washington, New York, and Maine will experience the most vivid displays, while observers in southern states like Oregon and Pennsylvania may also catch a glimpse. Sunspot 4455 is noted for its unusual 'anti-Hale' magnetic polarity, making it prone to producing strong solar flares. This solar activity is part of a broader trend as the sun approaches its solar maximum in 2024, a period marked by increased sunspot activity and potential for more extreme space weather events. Historical context is provided by events like the Carrington Event of 1859, which caused significant disruptions due to a massive solar storm.
