14-16 Jan: Very Low Solar Activity & Quiet Geomagnetic Conditions Expected

Quiet conditions expected next three days
14-16 Jan: Very Low Solar Activity & Quiet Geomagnetic Conditions Expected
published: Saturday, January 16, 2016 03:42 UTC

The next three days (14 - 16 January) are expected to be quiet; with very low solar activity levels. No G1 (Minor or greater) geomagnetic storming is expected. The negative polarity coronal hole high speed stream (CH HSS) that provided unsettled to active geomagnetic responses [with isolated periods of G1-Minor storming at higher latitudes] over the past three days (11-13 Jan) is beginning to rotate away from a geoeffective position, therefore solar wind speeds are expected to decrease to near ambient levels as the CH rotates further westward. The two sunspot groups are simple and have shown very little activity. Two lengthy, linear filaments exist; however neither has shown prolonged periods of instability. Should solar activity increase or a notable event take place, SWPC forecasters will update this post accordingly.
