A geomagnetic sudden impulse, indicating the arrival of the March 23 CME, was observed at the Hartland magnetometer (23 nT) at 20:09 UTC on March 25.
The geomagnetic field is expected to be at unsettled to active levels (below G1-Minor) early on March 26 as CME
Researchers at the UCL studying details of Coronal Mass Ejections (CMEs) have noticed that those eruptions have a surprising twin in the depths of space: the tendrils of gas in the Crab Nebula, which lie 6500 light-years away and are millions of
Solar activity was at moderate levels in last 24 hours (12:30 UTC). Region 1974 (S13W05, Fsc/beta-gamma-delta) continued to exhibit growth and separation in the intermediate spots, and was responsible for the majority of the flare activity throughout the
SWPC reported that solar activity continued at moderate levels today as both Regions 1967 (S13E01, Fkc/beta-gamma-delta) and 1968 (N10E03, Ekc/beta-gamma) produced M-class flare activity. These included an M2.6 at 06:34 UTC from Region 1968, an
From the start of October, Sun erupted 28 M-class and 3 X-class solar flares, sending the material into the space.
Solar activity is still raising with major X1.0 flare on October 28, 2013 and four moderate M-class flares. While our geomagnetic field is
In last 24 hours solar activity has been at moderate levels with many C-class flares detected from sunspots 1865, 1861 and from new approaching region behind the east limb. Active Region 1865 produced an M1.1 flare at 09:00 UTC. There are clear dimming
A spectacular filament eruption was observed yesterday August 6, 2013 at 02:04 UTC. A strong Coronal Mass Ejection (CME) has been seen following this energetic impulsive eruption and it does seem to have an earth-bound component which should impact the
A large prominence lifted off the northwest limb on July 21, 2013 and generated a Coronal Mass Ejection (CME), directed to the north and away from Earth.
STEREO Ahead and STEREO Behind COR2 images show the prominence flaring on July 22, 2013
SOHO's latest "Picture of the week" edition released great graphic illustration of combination of Sun-observing spacecrafts coverage of solar events.
From their positions near the Sun-Earth line, SDO and SOHO observed small CME on July 4, 2013. At
We saw increased geomagnetic activity for past two days as Kp index reached K=5, G1 geomagnetic storming level, on July 10. A minor CME hit Earth's magnetic field on July 9, 2013 at approximately 20:30 UTC and peaked during the early hours of
