Solar alert

Issued on 2023 Feb 27 1957 UTC

A major geomagnetic storm is currently ongoing, since 06:00 UTC today, February 27. The Kp-NOAA index remains continuously between 6 and 7. The K-Belgium index was 5 until, and it is now showing a value of 6. This geomagnetic storm is due to the arrival of the fast solar wind (with speed up to 880 km/s) that started to increase on February 26, at 21:00 UTC. The solar wind enhancement is believed to be the result of a combination of the expected fast wind from the equatorial coronal hole of negative polarity that transited the central meridian and the expected arrival of the coronal mass ejection observed in SOHO/LASCO on February 25 with the M6.3 flare.
