Moderate Geomagnetic Storm Watch For Sunday 25 April 2021 | National Oceanic and Atmospheric Administration

April 22, 2021 (NOAA) -- NOAA issued a G2 (moderate) geomagnetic storm watch for Sunday 25 April 2021.

A partial halo Coronal Mass Ejection (CME) was associated with a C3 flare from Region 2816 at 22/0435 UTC, the U.S. National Oceanic and Atmospheric Administration reported.

Space Weather Prediction Center forecasters analyzed this CME multiple times and determined a best WSA-Enlil model result.

This solution indicates an Earth-directed component and arrival early to mid-day on the 25 April UTC-day.

The forecast now calls for likely geomagnetic storm conditions, with the potential to reach G2 (Moderate) storm levels, therefore, a G2 geomagnetic storm watch has been issued for 25 April.

While forecast confidence in an Earth-directed component is fair, timing and intensity confidence is lower. Continue to follow our webpage for the latest information.
