At the beginning of the week, on December 23, a sunspot erupted, resulting in a coronal mass ejection (CME) being released into space, reports Spaceweather. This event caused a geomagnetic storm on Earth during these days, although it was not the strongest.
The National Oceanic and Atmospheric Administration's Space Weather Prediction Center has published a forecast for solar and geomagnetic activity on December 25. According to their data, a geomagnetic storm with a K-index of 5 is expected on Wednesday, which corresponds to a red level of danger.
A magnetic storm of similar strength will continue tomorrow, December 26, after which it will gradually subside, witnesses data from Meteoagent. However, this information may change, as active sunspot 3932 triggered a new strong solar flare of class M4.9 today, December 25.
