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)

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

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

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

Long duration M 1.2 solar flare erupted on March 15, 2013 and launched a Full-Halo Coronal Mass Ejection (CME) toward Earth. It hit Earth’s magnetic field at 06:01 UTC on March 17, 2013 and Geomagnetic K-index of 6 reached threshold on March 17, 2013 at 08:42

On March 12, 2013 a solar filament in the sun’s northern hemisphere erupted and launched Coronal Mass Ejection (CME). The source of the explosion was active region AR1690. A CME produced by the explosion is traveling north of the Earth line, but part of the CME
