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 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…
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…
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…
Our planet is passing through a stream of fast-moving, negative polarity solar wind. Geomagnetic storming reached G1 – Minor levels at 17:24 UTC. A G2 – Moderate warning is in effect for the rest of the UTC day. This is a recurrent CH HSS, responsible for G3 -…
A new round of geomagnetic storming is in progress on March 15, 2016. Solar wind parameters are enhanced since late March 14 due to the onset of a negative polarity coronal hole high speed stream (CH HSS) and are expected to remain like that through March 16….
A negative polarity, coronal hole high speed stream (CH HSS) became geoeffective early March 6, 2016, causing an increase in solar wind speeds and an enhanced interplanetary magnetic field. A G1 – Minor geomagnetic storm began at 17:28 UTC, increased to G2 -…
A geomagnetic storm reaching G1 – Minor levels is currently in progress due to the arrival of the co-rotating interaction region (CIR) associated with coronal hole 55. The proton flux might reach S1 – Minor levels in the period between February 16 and 18 due to the…
Prolonged effects of a partial-halo CME impact, produced by the filament eruption just of center disk late on January 14, 2016, is causing a G1 Minor geomagnetic storm on January 20, 2016. The CME reached our planet just before 21:00 UTC on January 18. Geomagnetic…
An active region currently positioned behind the northeast limb erupted with two M-class solar flares by 10:19 UTC on December 21, 2015. The first event started at 00:52, peaked at 01:03 as M2.8 and ended at 01:11 UTC. The second event started at 10:09, peaked at…
