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…
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 Coronal Mass Ejection (CME) produced by the X9.3 solar flare on September 6, 2017, reached our planet at 23:04 UTC on September 7, 2017, a full day earlier than it was expected. G3 – Strong geomagnetic storming started 23:25 and increased to G4 – Severe at 23:50…
G2 – Moderate geomagnetic storm conditions were observed early August 22, 2017 due to a sudden enhancement in solar wind environment. SWPC said conditions are not expected to increase any higher, with solar winds continuing to decrease as the day progresses….
Our planet is under the influence of a coronal hole high speed stream (CH HSS) which is causing isolated periods of G1 – Minor geomagnetic storming over the past 2 days, August 17 and 18, 2017. Meanwhile, solar activity is very low. There is only one numbered active…
A positive polarity coronal hole high speed stream (CH HSS) is affecting our planet and will continue to do so over the next three days. Over the past 24 hours, by 12:30 UTC on July 22, solar wind parameters as measured by DSCOVR spacecraft reflected the influence…
Our planet is under the influence of a positive polarity CH HSS which is causing geomagnetic storms reaching G1 – Minor levels. During the past 24 hours, solar wind parameters reflected the onset of a co-rotating interactive region (CIR) followed by the influence of…
A partial-halo coronal mass ejection (CME) produced on June 28, 2017 hit Earth's magnetic field at 17:12 UTC on July 1, almost 24 hours earlier than expected. The impact was weak but managed to spark a G1 – Minor geomagnetic storm 17 hours later. G1 Watch…
