Our planet is again under the influence of a recurring, positive polarity Coronal Hole High Speed Stream (CH HSS), which is causing isolated periods of G1 – Minor geomagnetic storming. Over the past 24 hours, solar wind parameters were indicative of the arrival of a…
A moderately strong solar flare measuring M1.1 at its peak erupted at 23:28 UTC on October 20, 2017 from the vicinity of old Region 2682, numbered 2673 two rotations ago. Radio signatures suggested and coronagraph imagery confirmed, a Coronal Mass Ejection (CME) was…
A powerful double solar flare eruption took place beyond the Sun's east limb early October 18, 2017. The responsible region is now rotating into Earth view and will be visible in a couple of days. The eruption was associated with a Type II (estimated velocity 1…
Our planet is under the influence of coronal hole high speed stream (CH HSS) for the third day in a row. The geomagnetic field was unstable, with isolated periods of G1 – Minor storm levels during the past two days and then increased to G2 – Moderate levels at 14:59…
Geomagnetic storming reaching G1 – Minor levels is underway as our planet moves through a stream of high-speed solar wind. At the same time, solar activity is at very low levels with no flare activity and a spotless Sun on its Earth-facing side. Over the past 24…
When charged particles from a solar storm reached Mars this month, they set off an aurora 25 times brighter and surface level radiation readings twice as high as any previous measurements. An unexpectedly strong blast from the Sun hit Mars this month, observed by…
A recurrent, polar-connected, positive-polarity coronal hole is affecting our planet since September 27. G1 – Minor geomagnetic storm levels were reached at 08:48 UTC on September 27, followed by G2 – Moderate levels at 20:24 UTC and then increased to G3 – Strong…
A stream of high-speed solar wind coming from a recurrent, polar-connected, positive-polarity coronal hole is affecting our planet today and causing geomagnetic storming. G1 – Minor geomagnetic storm levels were reached at 08:48 UTC and increased to G2 – Moderate…
Our planet is under the influence of a positive polarity coronal hole high speed stream (CH HSS) which is causing isolated periods of G2 – Moderate geomagnetic storming. Geomagnetic K-index of 5 (G1 – Minor) geomagnetic storm threshold was reached at 15:43 UTC. G2 -…
A major X8.2 solar flare that erupted at 16:06 UTC on September 10, 2017 from Region 2673, produced a powerful asymmetric full halo Coronal Mass Ejection (CME) and it appears one part of it is heading toward Earth. A glancing blow is expected late on September 13….
