A forecast Warning has been issued for G1 (Minor) geomagnetic storm conditions through 02 February, 2015 in response to a high speed solar wind stream. Storms at the G1 level are fairly common and pose little threat to technology or infrastructure.

However, people at high latitudes may observe the Aurora. Once the magnetometer network indicates a G1 storm is in progress, an Alert will be issued. You can sign up to receive Watches, Warnings, and Alerts under the Subscribe heading above.

The plot depicts solar wind parameters observed by the ACE spacecraft. The solar wind speed (yellow line) is rising over 700 km/s. Temperature (green line) is rising also. The total magnetic field (Bt) and z-component (Bz), the white and red lines, respectively, are disturbed and Bz has turned southward. These observations all suggest the influence of the anticipated coronal hole high speed solar wind stream.
