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 -…
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…
Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS) for several days now. Enhanced solar wind parameters are expected to continue through October 1, with G3 – Strong geomagnetic storm levels possible today. G2 – Moderate…
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…
During the past 24 hours, solar wind parameters transitioned from near background conditions to an enhanced state, causing G1 – Minor geomagnetic storming on Earth. This was most likely caused by the onset of co-rotating interaction region (CIR) ahead of a negative…
Earth is under continued influence of a positive polarity coronal hole high speed stream (CH HSS), which is now causing geomagnetic storms at high latitudes. K-index of 5 (G1 – Minor geomagnetic storm) threshold was reached at 08:59 UTC on September 1, 2016. …
A geomagnetic storm reaching G1 – Minor levels is currently in progress following the early arrival of July 17th Coronal Mass Ejection (CME). The interplanetary shockwave produced by the long duration C1 flare on July 17, initially expected to arrive early on July…
Solar wind parameters reflected a brief enhancement associated with the arrival of a co-rotating interaction region (CIR) and subsequent negative polarity coronal hole high speed stream (CH HSS) late June 22, 2016. A gradual increase in solar wind speeds began after…
