South Africa observed an extremely strong geomagnetic storm.

The South African National Space Agency said on the 20th that a geomagnetic storm triggered by a solar storm reached G5 level in South Africa in the early hours of the 20th local time. The South African National Space Agency said that on the 18th, a long-lasting X1.9-class solar flare triggered a coronal mass ejection, and the charged particles produced subsequently reached Earth, causing a geomagnetic storm in the Earth's magnetic field. This geomagnetic storm reached G4 level in South Africa on the evening of the 19th local time. In the early hours of the 20th, the South African National Space Agency's Space Weather Center in Hermanus, Western Cape Province, observed that the intensity of the local geomagnetic storm reached G5 level, with a Kp value of 9.
