The coronal hole high speed stream continues to cause geomagnetic responses to G1 (Minor) storming levels. Solar wind speeds over the past 24 hours have ranged from 675-750 km/s [that is nearly 400 km/s higher than normal background speeds]. The coronal hole high speed stream effects are expected to elicit G1-G2 (Minor-Moderate) conditions intermittently over the next 24 hours (29-30 September); as well as more intense activity in the northern latitudes (depicted in the graphic). Therefore a G2 Watch continues into 30 Sep and a G1 Watch on 01 October – as the high speed solar wind begins to slowly subside. Visit swpc.noaa.gov for updates
