A moderately strong solar flare reaching M2.0 erupted from Region 2017 on March 28, 2014 at 19:18 UTC. A Type II radiation sweep with estimated velocity of 528 km/s was registered at 19:18 UTC. Type II emissions typically indicate a Coronal Mass Ejection is
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
Active region 2014 (S14E20, Dsc/beta-gamma) produced a long duration C5 solar flare on March 23, 2014 at 03:48 UTC. This flare lasted several hours and thus produced energy equivalent to much stronger flares. A Coronal Mass Ejection (CME) associated with this event…
At 03:56 UTC today the Sun sent us its best equinox wishes with moderately strong M1.7 solar flare originating from Region 2010 (S15E27, Dac/beta). This was the largest event on the Sun in last 24 hours (by 12:30 UTC) and it was associated with a Type II
Near X-class solar flare reaching M9.3 erupted from departing Sunspot 1996 on March 12, 2013 at 22:34 UTC.
This decaying sunspot is located near eastern limb and generated CME was not geoeffective, however, it produced a R2 (Moderate) Solar Flare Radio Blackout
After major X4.9 solar flare that erupted on February 25 from Region 1990 [during its 3 rotation on the Earth side of the Sun] we almost had no day without a moderate eruption. Since then, solar observatories recorded 16 M-class solar flares ranging from M1.0 to M3.5. S
Active Region 1996, located in the northern hemisphere, produced moderate M3.5 solar flare at 03:50 UTC on March 11, 2014. This active region continues to rotate closer towards the northwestwern limb.

In the giant system that connects Earth to the sun, one key event happens over and over: solar material streams toward Earth and the giant magnetic bubble around Earth, the magnetosphere helps keep it at bay. The parameters, however, change: The particles streaming in
Aurora borealis is a normal event at high latitudes during geomagnetic storms but when they are seen as low as Slovenia (Zagarjev vrh, N46.03, E14.65) you know the event is rare and stunning for the observers. The following image was captured in Slovenia on
Coronal mass Ejection brushed Earth's magnetic field causing G2 (Moderate) Geomagnetic Storming late on February 27, 2014. The event was associated with the R3 (Strong) Solar Flare Radio Blackout event caused by February 25th X4.9 solar flare.
