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...

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...

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...
April 11, 2017
A G1 - Minor geomagnetic storm is in progress as of 08:14 UTC on April 4, 2017, due to Earth's proximity to the heliospheric current sheet (HCS) and weak influences of the southern polar, negative coronal hole high speed stream (CH HSS). Geomagnetic K-index of 5...

A moderately strong solar flare measuring M5.8 (R2 - Moderate) erupted from Region 2644 at 14:29 UTC on April 3, 2017. The event started at 14:19 and ended at 14:34 UTC. This is the 7th and the strongest M-class solar flare since late April 1, 2017. It is also the...
April 03, 2017
Departing Active Region 2644 erupted with seven M-class solar flares since late April 1, 2017. The series started with M4.4 on April 1 and was followed by M5.3, M2.3, M2.1 and M5.7 on April 2, and M1.2 and M5.8 on April 3. Multiple coronal mass ejections were...

Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS) which is causing geomagnetic storming. G1 - Minor geomagnetic storm threshold was first reached at 16:12 UTC on March 21, 2017. A G2 - Moderate geomagnetic storm warning was...
