A rare solar storm may light up the northern sky this week and could briefly affect satellites and power systems. Scientists warn that an incoming 'cannibal' coronal mass ejection (CME) may rival the extraordinary May 2024 storm.
The event occurs when one solar eruption overtakes another, merging into a single, larger wave of charged particles and magnetic fields. Sunspot AR4274 has produced multiple strong X-class flares since early November, making this storm particularly unusual.
