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...
September 27, 2017
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 powerful X8.2 solar flare erupted from Region 2673, located just around the visible disk, at 16:06 UTC on September 10, 2017, causing R3 - Strong radio blackout and a rapid increase in relativistic proton levels. Within just 3 hours, solar radiation storm reached...

The coronal mass ejection (CME) produced by the M5.5 solar flare on September 4, 2017 arrived at the DSCOVR spacecraft on September 6 at 23:08 UTC and at Earth 30 minutes later. The impact did not spark a geomagnetic storm, but the potential still exists as the CME...
September 07, 2017
A major X-class solar flare erupted from geoeffective Active Region 2673 peaking as X9.3 at 12:02 UTC on September 6, 2017. The event started at 11:53, peaked at 12:02 and ended at 12:10 UTC. This is the second X-class solar flare of the day. It comes just hours...
