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
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
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.

As forecasted yesterday Coronal Mass Ejection (CME) hit Earth's magnetic field around 03:00 UTC today. That's a second CME impact within 24 hours, and another round of auroras.
SWPC issued Geomagnetic K-index of 6 (G2 – Moderate) alert at 05:28
Earth is currently under the influence of a Coronal Mass Ejection (CME) and G2 (Moderate) geomagnetic storming has been observed. According to SWPC, this is likely the result of what was expected to be a near miss from an event originally observed on
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
High speed solar speed is creating brief periods of geomagnetic storming. High latitude skywatchers should be alert for auroras.
Solar activity has been at moderate levels for the most of the day. There are 8 active sunspot regions on the Earth side of the
Earth is now under the influence of a stronger than expected coronal hole high speed stream (CH HSS). G2 (Moderate) geomagnetic storming has been observed and continued low-level storming is possible over the next 24 hours as Earth remains under the influence of
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
An interplanetary shock wave from yesterday's CME hit Earth's geomagnetic field at 20:23 UTC today. At the time, Boulder station measured magnetic field Bz component deviation of 62 nT. A G1 (minor) geomagnetic storm is currently underway. High
