Sunday's CME sparked moderate (G2) geomagnetic storming

A G2 geomagnetic storm is now in progress following CME impact on Earth's magnetic field early on October 2, 2013. The ACE spacecraft detected a solar wind increase to above 600 km/s and the Bz component (IMF) initially tipped sharply south to -19nT.

Six years of observing the Earth's magnetosphere

There is still only a handful of spacecraft to watch for solar and magnetic storms but the number of observatories has been growing over the last six years. Today, these spacecraft have begun to provide the first multipoint measurements to better understand space

High-speed solar wind speed buffeting Earth's magnetic field - G1 geomagnetic storm in progress

A high-speed solar wind stream from a geoeffective coronal hole is buffeting Earth's magnetic field and causing geomagnetic storms around the poles. The Bz component of the interplanetary magnetic field (IMF) is rotating between north and south pointing

Solar wind stream buffeting Earth's magnetic field

During last 24 hours solar wind stream buffeted Earth's magnetic field causing geomagnetic storms around the poles. Geomagnetic conditions were short lived reaching G1 - Minor geomagnetic storm levels (Kp=5). At those levels weak power

G1 geomagnetic storm in progress (July 15, 2013)

A minor geomagnetic storm is currently in progress due to slow-moving CME that erupted on July 9, 2013 and swept past Earth on July 13, 2013. The Bz component of the interplanetary magnetic field (IMF) tipped sharply south late on July 14,

Strong G3 geomagnetic storm in progress (June 29, 2013)

As Earth passes through a new coronal hole high speed stream, backed by unidentified CME shock, a prolonged interval of south-pointing magnetism (southward Bz) is having a strong impact on Earth's geomagnetic field. On June 29, 2013 Planetary K-index

Solar wind stream buffers Earth magnetic field

Earth is currently inside a solar wind stream flowing in from the massive coronal hole on the Sun's northern hemisphere. Elevated solar wind speed (above 600 km/s) combined with a south tilting Bz component of Interplanetary magnetic field (IMF) is responsible

Moderate geomagnetic storm in progress (June 7, 2013)

A moderate G2 Geomagnetic Storm (Kp=6) is currently in progress due the arrival of the fast flow from the low-latitude coronal hole at the northern hemisphere.​ Bz component of Interplanetary Magnetic Field (IMF) has been tipping sharply

Geomagnetic storm still in progress (June 2, 2013)

The arrival of an interplanetary shock wave on May 31, 2013 caused geomagnetic storming that reached G2 (Moderate) geomagnetic storm levels on NOAA/SWPC storm scale during June 1, 2013. The solar wind speed remains elevated above 650 km/s. Currently, geomagnetic

Moderate G2 geomagnetic storm in progress (June 1, 2013)

G2 (Moderate) geomagnetic storming has been observed as Earth remains under the influence of a slow-moving Coronal Mass Ejection (CME). This event was not associated with a significant M1.0 solar flare from May 31, 2013 and is likely the result of a disappearing

Subsiding geomagnetic storm (May 25/26, 2013)

Geomagnetic storming, caused by May 22th M-class solar flare and its Coronal Mass Ejection (CME), is slowly subsiding. Plasma cloud reached our geomagnetic field on May 24, 2013. In the past 24 hours, Earth's magnetic field experienced three episodes of

Geomagnetic storm in progress, subsiding solar radiation storm (May 24, 2013)

The geomagnetic storm associated with the May 22, 2013 solar flare (M5.0) and corresponding Coronal Mass Ejection (CME) is ongoing. G1 (Minor) geomagnetic storm conditions have occurred as a result. According to NOAA/SWPC, continued, low-level

Strong (S3) solar radiation storm in progress (May 23, 2013)

Solar radiation storm reached S3 (Strong) levels at approximately 03:00 UTC on May 23, 2013. Strong solar radiation storm is still in progress due an M5.0 solar flare originating in departing Sunspot 1745 on the Sun's western limb. The M-class

Major G2 geomagnetic storm conditions expected as CME sweeps past Earth

NOAA/SWPC reported passage of an interplanetary shock, recorded by ACE spacecraft. The CME-driven shock was first seen at 22:21 UTC on May 19, 2013, a bit later than forecasters had predicted. A Geomagnetic Sudden Impulse was recorded at 23:11 UTC. This

G1 (Minor) Geomagnetic Storm in progress - May 18, 2013

G1 (Minor) Geomagnetic Storm conditions are now occurring due to the arrival of the CME from May 15, 2013. During G1 Geomagnetic Storm, weak power grid fluctuations can occur, minor impact on satellite operations is possible, aurora is commonly

Moderate M1.3 solar flare from Region 1748. Slight chance for minor geomagnetic storming today

Active Region 1748 erupted with moderate solar flare measuring M1.3 at 21:53 UTC on May 16, 2013. This was another noticeable activity from this region after 4 X-class flares erupted on May 13/14. (X1.7 and X2.8 on May 13th, X3.2 and X1.2 on May 14th) This

Geomagnetic storms - basic terms, data, plots and graphs

A coronal mass ejection (CME) that erupted on March 15, 2013, hit Earth's magnetic field at 06:00 UTC on March 17, 2013. The solar wind speed reached 700 km/s and sparked a moderately strong G2 (Kp=6) geomagnetic storm and minor S1 solar radiation
