A geomagnetic sudden impulse — CME produced by a long-duration C7.4 solar flare on December 7, was observed at DSCOVR satellite at the L1 point at 01:32 UTC on December 10. The total field reached 16 nT while wind speeds topped out near 571 km/s, producing a period…
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…
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….
Solar wind parameters in 24 hours ending 12:30 UTC today were indicative of a slightly enhanced and disturbed interplanetary magnetic field (IMF) due to weak coronal hole high speed stream (CH HSS) influences. Total IMF strength was variable, but steadily increased…
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…
Solar wind parameters over the past 24 hours were indicative of enhanced solar wind environment, likely caused by a combination of a glancing blow from a slow-moving Coronal Mass Ejection and influences of a negative polarity CH HSS. Total IMF strength was at 5 to 6…
A several degree long solar filament south of the Region 2741 disappeared by approximately 15:14 UTC on May 13, 2019. Initial analysis suggests an Earth-directed component is likely with this Coronal Mass Ejection (CME). This is the fifth Earth-directed CME since…
