Multiple coronal mass ejections (CMEs) produced on November 27 and 28, 2023, impacted Earth on November 30 and December 1, sparking G3 \u2013 Strong geomagnetic storm. Similarly to the last G3 storm, on November 5, spectacular aurora sightings were reported from both hemispheres.<\/strong><\/p>\n

The solar wind parameters observed during the 24-hour period ending at 00:30 UTC on December 2, 2023, signaled the arrival of multiple CMEs, initially detected on November 27 and 28. <\/p>\n

The first notable CME impact, which occurred at 23:37 UTC on November 30, led to an increase in solar wind velocity from about 335 km\/s (208 mph) to approximately 440 km\/s (273 mph). Concurrently, the total magnetic field strength showed a significant rise from 5 nT to 12 nT.<\/p>\n

A second CME, produced by M9.8 solar flare on November 28, was observed at 08:53 UTC on December 1, causing further escalations in solar wind speeds from approximately 406 km\/s (252 mph) to near 510 km\/s (317 mph). <\/p>\n
