Six years of observing the Earth's magnetosphere

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

Solar wind stream buffeting Earth's magnetic field

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)

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)

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

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)

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)

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)

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)

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
