G2 – Moderate Geomagnetic Storm Alert issued on April 2

A G2 – Moderate Geomagnetic Storm Alert was issued on April 2, 2026, after the geomagnetic K-index reached a value of 6 at 17:05 UTC. The alert remains active, highlighting a period of increased geomagnetic activity between 15:00 and 18:00 UTC.

According to the official alert, potential impacts are focused primarily poleward of 55 degrees geomagnetic latitude. Power grid fluctuations may occur in these high-latitude areas, and voltage alarms are possible in affected power systems. Spacecraft may encounter orientation irregularities, and there is a possibility of increased drag on low Earth-orbit satellites. Additionally, high frequency (HF) radio propagation may fade at higher latitudes. The aurora could potentially be visible as far south as New York, Wisconsin, and Washington state. This alert corresponds to the G2 – Moderate level on the NOAA Space Weather Scale.

The current geomagnetic storm conditions were triggered by the combined influence of a coronal mass ejection (CME) and the onset of a coronal hole high speed stream (CH HSS). Forecasts predict unsettled to G1-G2 (Minor-Moderate) storm levels for the remainder of April 2, 2026, with heightened activity expected as these influences persist.
