A pair of solar flares erupted near the eastern limb of the Sun at about 00:55 and 03:25 UTC on July 23, 2017 and were observed in STEREO-A EUVI 195 imagery. The source is Active Region 2665 which produced a long-duration M2.4 solar flare and Earth-directed CME on...

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...

A coronal mass ejection (CME) produced by the July 14th M2.4 long-duration solar flare hit Earth's magnetic field at 06:01 UTC on July 16, 2017. G2 - Moderate geomagnetic storming started 9 hours later. The S1 Minor solar radiation storm that started at 09:00...

Active Region 2665 produced a long-duration solar flare measuring M2.4 at its peak time on July 14, 2017. Today's event lasted for more than 2 hours; it started at 01:07, peaked at 02:09 and ended at 03:24 UTC. The eruption produced a coronal mass ejection (CME)...

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...

Big sunspot region 2665 (beta) erupted with an impulsive solar flare measuring M1.3 at its peak time on July 9, 2017. The event started at 03:09, peaked at 03:18 and ended at 03:37 UTC. The last time our star unleashed an M-class solar flare was on July 4, 2017....
July 09, 2017
Solar activity was at moderate levels on July 3, 2017, with 14 B-class and one impulsive M1.3 solar flare observed at 16:15 UTC. The M-class event started at 15:37 and ended at 16:18 UTC. The last time our star unleashed an M-class solar flare was on April 3, 2017....

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...

Earth is under the influence of a recurrent, negative polarity coronal hole high speed stream (CH HSS) today which is causing G1 - Minor geomagnetic storming. Solar wind speed increased to 548 km/s at 08:08 UTC while total field reached a maximum of 16 nT at 07:16...

A coronal mass ejection (CME) produced during the early UTC hours of May 23, 2017 hit Earth's magnetic field at 15:36 UTC on May 27, more than 24 hours after it was expected. Although the solar wind speed is relatively slow, the embedded magnetic field had a...

An eruption near the center of Earth-facing side of the Sun produced a partial HALO CME (coronal mass ejection) during the early UTC hours of May 23, 2017. The CME is weak, but it has an Earth-directed component. Arrival at Earth is expected around 12:00 UTC on May...

Geomagnetic storms reaching G2 - Moderate levels are expected over the next 48 hours due to the influence of a geoeffective coronal hole in combination with an Earth-directed component of coronal mass ejection (CME) produced on May 13. The first effects are expected...
May 15, 2017
A potent coronal hole has become geoeffective and possibly in a combination with an April 18 CME is causing geomagnetic storms reaching G2 levels. This is the second of two geoeffective coronal holes to affect Earth this week. The effects are expected to persist...
April 22, 2017
A G2 - Moderate geomagnetic storm conditions were reached at 04:33 UTC on April 20, 2017. This activity is a result of continued coronal hole effects, the first of two expected to affect our planet this week. The geomagnetic field reached G1 - Minor levels during...

Earth is under the influence of a recurrent, positive polarity coronal hole high speed stream (CH HSS). A G1 - Minor geomagnetic storm began at 05:59 UTC today. Solar wind parameters, as measured by the DSCOVR spacecraft, continued at mostly nominal levels over the...

An approximate 14 degree solar filament eruption began at 20:25 UTC on April 9, 2017, from the northeast quadrant of the Sun. The event generated a coronal mass ejection (CME) and a glancing blow is possible on April 15. The CME was first observed in SOHO/LASCO C2...
