Our planet is under the influence of a positive polarity Coronal Hole High Speed Stream (CH HSS) over the past 24 hours. Geomagnetic storms reaching G2 – Moderate levels were registered November 5. Solar wind parameters reflected the passage of a Solar Sector…
A weak positive polarity Coronal Hole High Speed Stream (CH HSS) affecting our planet since late June 17, 2018, sparked a G1 – Minor geomagnetic storm at 02:56 UTC on June 18. Solar wind parameters, as measured by the DSCOVR spacecraft located at the L1 point, were…
A negative polarity Coronal Hole High Speed Stream (CH HSS) is affecting our planet today, sparking G1 – Minor geomagnetic storming. G1 threshold was reached at 13:29 UTC on June 1, 2018. Solar wind parameters became enhanced over the past 24 hours due to the effect…
G2 – Moderate geomagnetic conditions were observed on May 6, 2018 in response to the influence of a negative polarity coronal hole high speed solar wind stream. G1 – Minor geomagnetic storm conditions were first observed at 17:59 UTC on May 5, followed by G2 at…
A G2 – Moderate geomagnetic storm threshold was reached at 08:25 UTC on April 20, 2018 and G2 warning is in now in effect until 12:00 UTC. An interplanetary shock wave hit Earth's magnetic field around 23:50 UTC on April 19, Dr. Tony Phillips of SpaceWeather.com…
A persistent negative polarity coronal hole high speed stream (CH HSS) sparked G2 – Moderate geomagnetic storm on March 18, 2018. A gradual return to background levels is expected on March 19 as CH HSS influence subsides. However, enhanced solar wind parameters are…
Geomagnetic storms caused by negative polarity, south polar coronal hole high speed stream (CH HSS) reached G1 – Minor levels early Tuesday, February 27, 2018. Solar wind parameters are expected to further increase today and a G2 – Moderate geomagnetic storm warning…
An isolated interval of G1 – Minor geomagnetic storm conditions was observed early February 19, 2018, due to the influence of negative polarity coronal hole high speed stream (CH HSS). Solar activity over the past 24 hours was at very low levels. Earth-facing side…
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…
Our planet is under the influence of a coronal hole high speed stream (CH HSS) which is causing isolated periods of G1 – Minor geomagnetic storming over the past 2 days, August 17 and 18, 2017. Meanwhile, solar activity is very low. There is only one numbered active…
