A significant space weather event has prompted the National Oceanic and Atmospheric Administration (NOAA) to issue a Geomagnetic Storm Alert.
The Space Weather Message Code ALTK07, issued at 1952 UTC on April 19, 2024, indicates that the geomagnetic K-index has reached a value of 7, crossing the threshold at 1951 UTC during the synoptic period of 1800-2100 UTC.
Space experts initially anticipated the storm’s intensity to fluctuate between a G1 and G2 level, potentially escalating to G3 by Sunday.
However, the unpredictable nature of space weather has manifested itself, with a severe G3-level storm materializing within the last 24 hours.
The alert, classified as a G3 — Strong event on the NOAA Space Weather Scale, suggests that the area of impact is primarily poleward of 50 degrees Geomagnetic Latitude.
