Space Weather Outlook for October 24 to 30

Minor Geomagnetic storms are forecast for this week.

A category G1 (Minor) geomagnetic storm occurred on 19 October due to high-speed solar winds related to a coronal hole. Geomagnetic storms are disturbances in the geomagnetic field caused by gusts in the solar wind that blows by Earth, and can cause a variety of problems at the surface, if they are strong enough.

The forecast calls for Category G1 (Minor) geomagnetic storms are expected during 25 - 26 October due to coronal hole effects. As a result, weak auroral displays are likely late this week. Unfortunately, it appears that there will be considerable cloud cover, making for fair to poor viewing.

G1 - Minor storms - may have the following affects on earth bound systems: In power systems, weak power grid fluctuations can occur. For spacecraft, there may be minor impact on satellite operations. Other possible affects include migratory animals are affected at this and higher levels; aurora is commonly visible at high latitudes (North Dakota, northern Minnesota and Maine)

The Space Weather Prediction Center continually monitors and forecasts Earth’s space environment; provides accurate, reliable, and useful solar-terrestrial information; conducts and leads research and development programs to understand the environment and to improve services; advises policy makers and planners; plays a leadership role in the space weather community; and fosters a space weather services industry. Space Weather Prediction Center is the Nation’s official source of space weather alerts and warnings.
