CME hits Earth, sparking G2 – Moderate geomagnetic storm
A coronal mass ejection (CME) produced by a large filament eruption at 05:21 UTC on April 11, 2022 reached Earth around midnight UTC on April 14, sparking G2 – Moderate geomagnetic storm.
G3 – Strong geomagnetic storm in progress, G3 or greater – Strong to Extreme warning in effect
An equatorial, negative polarity coronal hole high speed stream (CH HSS) coupled with waning coronal mass ejection (CME) influence produced a G3 – Strong geomagnetic storm conditions early April 10, 2022. Conditions could further escalate and even reach G4 – Strong or G5 – Extreme conditions.
Solar wind parameters indicate the arrival of a slow-moving CME
Solar wind parameters over the past 12 hours indicated the arrival of a slow-moving Coronal Mass Ejection (CME), likely produced on April 10. A period of G1 – Minor storming began at 08:59 UTC on April 15. Another enhancement in parameters is expected on April 16…
Negative polarity CH HSS sparks G1 – Minor geomagnetic storm and auroras in the lower 48
Earth is under the influence of a negative polarity coronal hole high speed stream, sparking G1 – Minor geomagnetic storm and auroras as low as Michigan and Wisconsin, U.S. Enhanced solar wind parameters were observed on March 13, 2021, due to co-rotating…
CH HSS sparks G1 – Minor geomagnetic storm, G2 – Moderate warning
A recurrent, positive polarity coronal hole high speed stream (CH HSS) is affecting our planet since September 23, sparking active to G1 – Minor geomagnetic storm conditions. A G2 – Moderate geomagnetic storm warning was issued at 08:07 UTC today. In 24 hours to…
Series of coronal holes spark G1 – Minor geomagnetic storming
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…
G1 – Minor geomagnetic storm in progress
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 seen over Norway’s Lofoten Islands
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 under the influence of positive polarity CH HSS, G2 – Moderate geomagnetic storm
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…
G1 – Minor Geomagnetic Storm Watch in effect for October 24 and 25
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…
