CME hits Earth, sparking G2 – Moderate geomagnetic storm
A coronal mass ejection (CME) produced by a large filament eruption at 05:21 UTC on April 11, 2022 reached Earth around midnight UTC on April 14, sparking G2 – Moderate geomagnetic storm.
CME hits Earth sparking G2 – Moderate geomagnetic storm
A coronal mass ejection (CME) produced by the long-duration C2 solar flare on March 10/11, 2022, hit Earth early March 13, sparking G2 – Moderate geomagnetic storming. Disturbed conditions are expected to continue into March 14 and 15. The CME started around 18:00…
G2 – Moderate geomagnetic storm watch in effect
A G2 – Moderate geomagnetic storm watch is in effect for February 2, 2022, after a long-duration M1.1 solar flare produced an asymmetric, full-halo coronal mass ejection (CME) at 23:32 UTC on January 29. The CME is expected to reach Earth late February 1 or early…
CH HSS sparks G2 – Moderate geomagnetic storm
Our planet entered a stream of fast-moving solar wind on January 18, 2022, sparking G2 – Moderate geomagnetic storm. A slightly enhanced solar wind environment is anticipated today as CH HSS effects taper, followed by a minor enhancement due to glancing blow effects…
CME impacts Earth, sparks G2 – Moderate geomagnetic storm
Coronal mass ejection (CME) produced by M1.6 solar flare at 06:40 UTC on October 9, 2021, reached DSCOVR spacecraft at 01:48 UTC and Earth at 02:30 UTC on October 12, 2021. The impact sparked a G2 – Moderate geomagnetic storm. In 24 hours to 00:30 UTC on October 12,…
CME impacts Earth, sparking G3 – Strong geomagnetic storm
A coronal mass ejection (CME) produced by a filament eruption around 10:00 UTC on May 9, 2021, has reached Earth at 06:43 UTC on May 12. G3 – Moderate geomagnetic storm levels were observed at 12:59 UTC. The CME arrived at the DSCOVR spacecraft at 05:47 UTC. Solar…
Negative polarity CH HSS sparks G2 – Moderate geomagnetic storm
Earth is under the influence of negative polarity coronal hole high speed stream (CH HSS) over the past 24 hours, sparking G2 geomagnetic storming. The source is a polar connected coronal hole located in the Sun's southern hemisphere. Geomagnetic K-index of 5…
Negative polarity CH HSS sparks G2 – Moderate geomagnetic storm
Earth is under the influence of a negative polarity coronal hole high speed stream (CH HSS) on March 1, 2021, sparking G1 – Minor and G2 – Moderate geomagnetic storming. Solar wind speed started increasing late February 28, from 369 km/s at 22:00 UTC to 521 km/s at…
Earth under the influence of positive polarity CH HSS, G2 – Moderate geomagnetic storm
Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS). This is causing G1 – Minor to G2 – Moderate geomagnetic storming. Solar wind parameters were at background levels until about 06:00 UTC on October 24 when co-rotating…
G2 – Moderate Geomagnetic Storm Watch in effect
The solar wind environment is expected to become enhanced and disturbed later on September 27, 2019 (UTC). G1 – Minor Geomagnetic Storm Watch is in effect for September 27, G2 – Moderate for September 28. Quiet to unsettled geomagnetic field conditions are expected…
