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 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
Solar activity increased rapidly in the past two days with three M-class and three major X-class solar events. The latest recorded is the strongest flare so far this year, recorded as X3.2 on May 14, 2013 at 01:17 UTC. This event was associated with Type II and
A new active region behind east limb produced powerful X1.7 solar flare on May 13, 2013 at 02:15 UTC. This event was associated with strong R3 Radio Blackout Alert, Type II Radio Emission and 10 cm Radio Burst.
This was the strongest solar flare of
On May 1, 2013, Active Region just around the left edge of the Sun erupted with a huge coronal mass ejection (CME). The video bellow shows combined imagery from NASA’s SDO, SOHO and STEREO heliophysics fleet.
Solar Dynamics Observatory (SDO) provided a
Heliophysics scientists study energy transformation from one event to the other and which electromagnetic waves create which conditions near Earth. Space weather effects can disrupt satellites in space, so scientists need to understand the system in even more detail.
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
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
Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines
Sun erupted slow-moving Coronal Mass Ejection (CME) on February 19, 2013. Goddard Space Flight Center reported that the bulk of the plasma cloud was directed to the north of Earth. Still, we can expect a glancing blow around February 22, 2013. Minor to moderate
