The solar wind environment is expected to become enhanced and disturbed later on September 27, 2019 (UTC). G1 – Minor Geomagnetic Storm Watch is in effect for September 27, G2 – Moderate for September 28. Quiet to unsettled geomagnetic field conditions are expected…
Our planet has entered a stream of fast-moving solar wind flowing from a large positive polarity coronal hole. A G1 – Minor Geomagnetic Storm Watch is in effect for August 31 and G2 – Moderate for September 1. Solar wind parameters reflected a slow regime through…
An isolated, negative polarity Coronal Hole High Speed Stream (CH HSS) is affecting our planet on February 27 and 28, 2019, causing isolated periods of geomagnetic storming. Solar winds over the past 24 hours were indicative of an anticipated Solar Sector Boundary…
A weak solar flare measuring C5.0 at its peak erupted from Active Region 2733 at 13:22 UTC on January 26, 2019. The eruption started at 13:12 and ended at 13:34 UTC. This was the strongest solar flare since February 18, 2018. It was preceded by B1.5 at 03:49 UTC,…
A large negative polarity coronal hole is affecting our planet, causing G1 – Minor geomagnetic storming. Geomagnetic K-index of 5 (G1 – Minor geomagnetic storm) threshold was reached at 01:37 UTC, January 5, 2019. Solar wind parameters, as measured by the DSCOVR…
A positive polarity coronal hole high speed stream (CH HSS) is affecting our planet since late December 27, sparking G1 – Minor geomagnetic storm. Periods of active conditions are likely through December 29 followed by quiet to unsettled activity on December 30…
Our planet is under the influence of a positive polarity Coronal Hole High Speed Stream (CH HSS) over the past 24 hours. Geomagnetic storms reaching G2 – Moderate levels were registered November 5. Solar wind parameters reflected the passage of a Solar Sector…
Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS) on October 7 and 8, 2018. G1 – Minor geomagnetic storm conditions were observed at 16:22 UTC and 20:42 UTC on October 7, 2018. A G2 warning has been issued and is valid until…
A G2 – Moderate geomagnetic storm watch has been issued for September 11, 2018 due to the onset of positive polarity coronal hole high speed stream. Solar wind parameters over the past 24 hours were descriptive of the passage of Co-rotating Interaction Region (CIR)…
A weak positive polarity Coronal Hole High Speed Stream (CH HSS) affecting our planet since late June 17, 2018, sparked a G1 – Minor geomagnetic storm at 02:56 UTC on June 18. Solar wind parameters, as measured by the DSCOVR spacecraft located at the L1 point, were…
