Geomagnetic storm predicted

NOAA forecasters say there is a 50% chance of G1-class geomagnetic storms on Jan. 1st when a high-speed stream of solar wind engulfs Earth’s magnetic field.

G1 storms are relatively minor, having little effect on satellites and power grids. However, they can spark intense auroras around the Arctic Circle and may disorient animals that use magnetic cues for navigation at high latitudes.

Geomagnetic storms likely this week

A large hole has opened in the sun’s atmosphere, and it is spewing a stream of solar wind toward Earth. Estimated time of arrival: Oct. 24th.

First contact with the gaseous material is expected to produce minor G1-class geomagnetic storms, intensifying to moderately strong G2-class storms on Oct. 25th as Earth moves deeper into the stream.

Arctic sky watchers can expect to witness bright auroras. The lights could descend to lower latitudes as well, with sightings in northern-tier US states along a line from Maine to Washington.

A hole in the Sun’s atmosphere turns toward Earth

Spewing a stream of solar wind as fast as 700 km/s (1.6 million mph), a hole in the sun’s atmosphere is turning toward Earth.

Forecasters expect the stream to reach our planet on June 15th or 16th with a 40% chance of minor G1-class geomagnetic storms when it arrives.

High-latitude sky watchers should be alert for auroras in the nights ahead, especially in the southern hemisphere where deepening autumn darkness favors visibility.

Geomagnetic storm underway

A moderately strong G2-class geomagnetic storm is underway on May 27-28 as Earth moves through the wake of a CME that swept past our planet just hours ago.

High-latitude sky watchers should be alert for auroras, especially in the southern hemisphere where deepening autumn darkness favors visibility.
