According to data provided by the National Oceanic and Atmospheric Administration (NOAA), a significant geomagnetic storm impacted Earth over the course of the day. The most intense phase of the storm was recorded between 6 a.m. and approximately 9 a.m., when the geomagnetic field activity index, Kp, registered a reading of 7, corresponding to a G3 strength, classified as a strong storm.
Following this peak activity, the geomagnetic storm began a period of weakening. By noon, the activity had decreased to a Kp of 6, indicating an average storm level. Forecasts suggested a period of calming between 3 p.m.
and 6 p.m. However, the storm was projected to re-strengthen slightly between 6 p.m. and 9 p.m., although the Kp index was expected to drop to 5, signifying a G1 strength, or a weak storm.
NOAA utilizes a five-tiered scale to measure geomagnetic storm intensity. This scale defines G1 as minor, G2 as moderate, G3 as strong, G4 as severe, and G5 as extreme. This classification system allows meteorologists to monitor the potential effects of the geomagnetic storm on technology and infrastructure.
Understanding these fluctuations is crucial, as G3 and stronger geomagnetic storms can affect various systems across the globe.
