Our planet is under the influence of a series of coronal holes since August 25, 2020, sparking unsettled to G1 – Minor geomagnetic storm conditions. The effect is expected to continue through at least September 2. G1 – Minor geomagnetic storm threshold was first…
A negative polarity, southern crown coronal hole extension has moved into a geoeffective position enhancing the solar wind environment. Unsettled levels are expected on April 21 as high speed stream (HSS) effects persist. By late April 22 (UTC), a positive polarity…
Rare, vivid blue auroras were seen over the night sky of Norway's Lofoten Islands on Tuesday, February 18, 2020. Photographer Matthew Steinberg captured the majestic view, which he was able to finally witness after an entire day of snow, sleet, and heavy winds….
Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS). This is causing G1 – Minor to G2 – Moderate geomagnetic storming. Solar wind parameters were at background levels until about 06:00 UTC on October 24 when co-rotating…
A recurrent, positive polarity coronal hole high speed stream (CH HSS) is anticipated to rotate into an Earth-connected position on October 24. As a result, a G1 – Minor Geomagnetic Storm Watch is in effect for Thursday and Friday, October 24 and 25, 2019. A…
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…
