Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS) which is causing geomagnetic storming. G1 – Minor geomagnetic storm threshold was first reached at 16:12 UTC on March 21, 2017. A G2 – Moderate geomagnetic storm warning was…
A negative polarity, polar-connected coronal hole high speed stream (CH HSS) is affecting Earth for the second day in a row, sparking geomagnetic storms reaching G2 Moderate levels. Over the past 24 hours, the solar wind environment was elevated due to the passage…
Earth is under the influence of a recurrent, polar-connected coronal hole which has sparked G1 (Minor) geomagnetic storming today. Unsettled to active conditions, with G1 storming likely, are expected to continue through March 2. Geomagnetic K-index of 5 (G1 – Minor…
Our planet is under the influence of a recurrent, positive polarity coronal hole high speed stream since around 20:48 UTC on February 23. This is causing G1 geomagnetic storming. Geomagnetic K-index of 5 (G1 – Minor geomagnetic storm) threshold was first reached at…
A recurrent, negative polarity coronal hole high-speed stream (CH HSS) is affecting our planet causing isolated periods of G1 Minor geomagnetic storming and vivid auroras. High-speed solar wind speed hit Earth late January 31, 2017. Geomagnetic K-index of 5 (G1 -…
Earth is under the influence of a positive polarity coronal hole high speed stream today, December 21, 2016, which is causing geomagnetic storms reaching G2 Moderate levels. Shortly after 04:00 UTC on December 21, solar wind speeds increased to just over 500 km/s,…
A geomagnetic storm is currently in progress due to ongoing negative polarity coronal hole high speed stream (CH HSS) influence. The G1 Watch is in effect for the next three days. Geomagnetic K-index of 5 (G1 – Minor geomagnetic storm) threshold was first reached at…
Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS). A sudden escalation in overall planetary geomagnetic response from a favorable solar wind environment and elevated solar wind streams triggered periods of G1 and G2…
Earth is passing through a stream of high speed solar wind produced by a recurrent, polar connected, positive polarity coronal hole. This is causing isolated periods of G1 class geomagnetic storming. G2 – Moderate geomagnetic storm watch is in effect for October…
A filament in Sun's northeast quadrant erupted between 15:00 and 17:00 UTC on Saturday, October 8, 2016, producing an asymmetric, partial-halo CME. The CME, although faint, was first observed in LASCO C2 imagery beginning 00:48 UTC on October 9. It reached ACE…
