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…
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 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…
