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.

Solar wind parameters indicate the arrival of a slow-moving CME

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…

CH HSS sparks G1 – Minor geomagnetic storm, G2 – Moderate warning

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

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

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….

G1 – Minor Geomagnetic Storm Watch in effect for October 24 and 25

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…
