Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS) for several days now. Enhanced solar wind parameters are expected to continue through October 1, with G3 - Strong geomagnetic storm levels possible today. G2 - Moderate...

High-speed solar wind from a recurrent coronal hole has sparked another round of geomagnetic storming on Earth. The solar wind environment is expected to remain elevated but steady through the rest of the UTC day before becoming further enhanced on September 28 and...

During the past 24 hours, solar wind parameters transitioned from near background conditions to an enhanced state, causing G1 - Minor geomagnetic storming on Earth. This was most likely caused by the onset of co-rotating interaction region (CIR) ahead of a negative...

Earth is under continued influence of a positive polarity coronal hole high speed stream (CH HSS), which is now causing geomagnetic storms at high latitudes. K-index of 5 (G1 - Minor geomagnetic storm) threshold was reached at 08:59 UTC on September 1, 2016. ...

After Active Region 2567, the source of 7 M-class and numerous C-class solar flares between July 21 and 24, rotated away from the visible disk, our Earth facing Sun is again spotless. This is the third 'spotless Sun' since June 3, and although it is a...

Three strong solar flares erupted from Active Region 2567 early on July 23, 2016 - M5.0, M7.6, and M5.5. A Coronal Mass Ejection (CME) was produced during the third one, however, this region is not in a position to produce Earth-directed CMEs. The first flare...

After more than 3 months without any significant solar flare, our sun produced two consecutive M-class flares early on July 21, 2016. The source was Active Region 2567 ('beta-gamma' / 'beta'), currently moving out of its geoeffective position....

A geomagnetic storm reaching G1 - Minor levels is currently in progress following the early arrival of July 17th Coronal Mass Ejection (CME). The interplanetary shockwave produced by the long duration C1 flare on July 17, initially expected to arrive early on July...
July 20, 2016
Although solar activity was at low levels on July 17, 2016, geoeffective Active Region 2567 ('beta-gamma') managed to produce a long duration C1 solar flare. The event peaked at 06:42 UTC, producing a faint, asymmetric halo Coronal Mass Ejection (CME)....

Solar wind parameters reflected a brief enhancement associated with the arrival of a co-rotating interaction region (CIR) and subsequent negative polarity coronal hole high speed stream (CH HSS) late June 22, 2016. A gradual increase in solar wind speeds began after...

A co-rotating interaction region (CIR) - the transition zone between slow- and fast-moving streams of solar wind - has hit Earth's magnetic field on June 14, 2016, sparking geomagnetic storms. As of 19:55 UTC, a G2 - Moderate geomagnetic storm is in progress and...
June 14, 2016
A recurrent, negative polarity coronal hole high speed stream (CH HSS) has hit Earth's magnetic field causing geomagnetic storms on June 5, 2016. A G2 (Moderate) geomagnetic storm watch is currently in effect. This same CH HSS has affected Earth on May 8 with...

A G3 - Strong geomagnetic storm conditions were observed beginning 05:59 UTC on May 8, 2016. G2 - Moderate to G3 - Strong geomagnetic storm conditions are expected through the rest of the day and possibly into May 9 and 10. This activity is caused by a recurrent,...

Enhanced solar wind conditions have fueled elevated geomagnetic field activity early May 2, 2016. Geomagnetic storms reaching G2 - Moderate levels have been observed. Geomagnetic K-index of 5 (G1 - Minor geomagnetic storm) threshold was first reached at 00:37 UTC on...

An impulsive solar flare measuring M6.7 (R2 - Moderate radio blackout) erupted from Active Region 2529 at 00:29 UTC on April 18, 2016. The event started at 00:14 and ended at 00:39 UTC. This was the first M-class solar flare since M1.1 on February 15, 2016, the...

Earth is under the influence of negative polarity coronal hole high speed stream (CH HSS) since late April 12, 2016. This is causing isolated periods of G1 - Minor geomagnetic storming. Geomagnetic K-index of 5 (G1 - Minor geomagnetic storm) threshold was first...
April 14, 2016
A geomagnetic storm reaching G1 - Minor levels is currently in progress as Earth enters a stream of positive polarity high-speed solar wind. Geomagnetic K-index of 5 (G1 - Minor geomagnetic storm) threshold was reached at 20:40 UTC on April 7: Space Weather Message...
