High-speed solar wind from a recurrent coronal hole has sparked another round of geomagnetic storming on Earth. The solar wind environment is expected to remain elevated but steady through the rest of the UTC day before becoming further enhanced on September 28 and 29. This feature produced G2 geomagnetic storming during its last rotation through the Earth side of the Sun and similar conditions are expected during this one too.
G1 Minor geomagnetic storm threshold was reached at 01:19 UTC on September 27, 2016.
Unsettled to active geomagnetic conditions are expected to continue into September 28, before the onset of the larger, northern polar crown connected CH HSS.
Isolated periods of G1-G2 (Minor-Moderate) storm levels are possible today and tomorrow, as well as throughout September 29.
A G2 Watch has been issued for September 28 and 29.
