S3 - Strong solar radiation storm in progress, active alert for aircrews and pregnant passengers

A powerful X8.2 solar flare erupted from Region 2673, located just around the visible disk, at 16:06 UTC on September 10, 2017, causing R3 - Strong radio blackout and a rapid increase in relativistic proton levels. Within just 3 hours, solar radiation storm reached...

Major solar flares erupting behind the northeast limb

A major solar flare was detected behind Sun's northeast limb on September 1, 2014. STEREO Behind spacecraft, watching farside of the Sun, captured what is most likely an X-class solar flare starting at 11:05 UTC.This major solar flare was associa

Subsiding geomagnetic and solar radiation storms

Geomagnetic storm sparked by a combination of CMEs from last couple of days is now subsiding. We might still see uptick today but it will most likely remain below G1 levels.At 10:57 UTC on April 20, a 24 nT geomagnetic sudden impulse (interplanet

S1 (minor) solar radiation storm in progress after M7.3 solar flare on April 18

Earth is currently under the influence of S1 (minor) solar radiation storm created as a result of yesterday's M7.3 solar flare. Our planet is showered with highly energetic solar particles (primarily protons) released from the flare site. Extende

Geomagnetic storm in progress, subsiding solar radiation storm (May 24, 2013)

The geomagnetic storm associated with the May 22, 2013 solar flare (M5.0) and corresponding Coronal Mass Ejection (CME) is ongoing. G1 (Minor) geomagnetic storm conditions have occurred as a result. According to NOAA/SWPC, continued, low-level

Moderate (G2) geomagnetic storm and minor solar radiation storm in progress

As expected, an interplanetary shock wave associated with the "double CME" of June 13-14 hit Earth's magnetic field today around 09:57 UTC.ACE Spacecraft detected an incoming shock passage around 09:00 UTC this morning and a Geomagnetic Sudden Impulse was recorded by

Long duration C-class event generated minor S1 radiation storm on Earth and hurled CME toward Mars

The proton levels reached S1 Minor Radiation Storm threshold today. The Solar X-Rays also detected a long duration C-Class event during the early hours of Sunday morning and this generated a Coronal Mass Ejection (CME). It appears that the plasma cloud was directed

M5.1 solar flare generated S2 solar radiation storm

A strong solar flare reaching M5.1 took place at 01:47 UTC Thursday morning. The flare was centered around Sunspot 1476 near the northwest limb. A bright CME was generated but because of the spots location, the plasma cloud will be headed mostly to the west.The
