A mild (Kp=5) geomagnetic storm is underway

A mild (Kp=5) geomagnetic storm is underway

This is the third day in a row that geomagnetic storms have circled the poles. A mild (Kp=5) geomagnetic storm is underway. It looks like it subsiding now. High-latitude sky watchers should be alert for auroras. The source of this activity is a high-speed solar wind stream buffeting Earth's magnetic field. (SpaceWeather)

The magnetic field of sunspot 1465 has relaxed, reducing the chances of strong flares from the region.

Stay tuned for more updates!

3-day Solar-Geophysical Forecast issued Apr 25 22:00 UTC

Solar Activity Forecast: Solar activity is expected to remain at low levels with a slight chance for M-class activity for the next three days (26 - 28 April).

Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels with isolated minor storm periods on day one (26 April) as the 23 April CME is expected to become geoeffective. Quiet to unsettled levels with isolated active periods are expected on day two (27 April) as effects of the CME wane. By day three (28 April), mostly quiet conditions are expected.
