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

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

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

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 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
