Geomagnetic activity forecast for the period

November 06 - November 12, 2026

Quiet:	Nov 10 - 11
Unsettled:	Nov 8 - 9, 11 - 12
Active:	Nov 6 - 9
Minor storm:	Nov 6 - 8
Major storm:	possible about Nov 7
Severe storm:	0
Geomagnetic activity summary:	Next days, we expect a significant geomagnetic activity increase because of a large coronal hole 09/-4. Next days, we expect unsettled to active level generally with a possible storming event. We expect at most minor storm event, a major storm event is possible but unlikely. Since Sunday, November 8, we expect a partial decrease to at most unsettled level followed by a quiet to unsettled episode. At the end of currently forecasted period, a partial activity increase to unsettled to active level can be expected.

Geomagnetic activity forecast for the period

November 06 - November 12, 2026

Remarks:

Weekly Commentary on the Sun, the Magnetosphere, and the Earth's Ionosphere, November 5, 2026

During the last third of October, solar activity declined steadily. The increase did not begin until two weeks later while could last another two weeks. Low geomagnetic activity—particularly between October 24 and 29—led to an improvement in shortwave ionospheric propagation on a global scale, despite low solar activity.

The current increase in solar activity will continue into the first half of November. Given regular seasonal changes, a continued improvement in ionospheric shortwave propagation can be expected on most days during the first half of November.
