CME impacts Earth, sparks G2 – Moderate geomagnetic storm

CME impacts Earth, sparks G2 – Moderate geomagnetic storm

Coronal mass ejection (CME) produced by M1.6 solar flare at 06:40 UTC on October 9, 2021, reached DSCOVR spacecraft at 01:48 UTC and Earth at 02:30 UTC on October 12, 2021. The impact sparked a G2 – Moderate geomagnetic storm. In 24 hours to 00:30 UTC on October 12,…

Moderately strong M2.8 and M1.8 solar flares erupt from AR 2871

Moderately strong M2.8 and M1.8 solar flares erupt from AR 2871

A moderately strong solar flare measuring M2.8 at its peak erupted from Active Region 2871 at 04:42 UTC on September 23, 2021. The event started at 04:35 and ended at 04:50 UTC. The flare was associated with a Type II Radio Emission at 04:44 UTC with an estimated…

G2 – Moderate geomagnetic storm watch in effect

G2 – Moderate geomagnetic storm watch in effect

A G1 – Minor geomagnetic storm watch is in effect for September 1 and a G2 – Moderate for September 2, 2021. The geomagnetic field is expected to be at quiet to unsettled conditions on August 31 due to the delayed anticipated passage of the August 26th coronal mass…

Moderately strong M4.7 solar flare erupts from geoeffective AR 2860

Moderately strong M4.7 solar flare erupts from geoeffective AR 2860

A moderately strong solar flare measuring M4.7 at its peak erupted from geoeffective Active Region 2860 at 06:15 UTC on August 28, 2021. The event started at 05:39 and ended at 06:23 UTC. The flare event follows increased solar activity with numerous c-class flares…

Glancing blow CME possible on July 23, G1 Geomagnetic Storm Watch

Glancing blow CME possible on July 23, G1 Geomagnetic Storm Watch

A glancing blow CME from the July 20 eruption could bring a chance for G1 – Minor geomagnetic storm condition on July 23, 2021. As a result, a G1 Geomagnetic Storm Watch is in effect. A ~4-degree solar filament centered at approximately N25E65 erupted from the…

The Sun sends us a wake-up call

The Sun sends us a wake-up call

Two powerful solar events erupted from the Sun over the past couple of days. While they both missed Earth, 'we are very lucky they did,' Ben Davidson of the Suspicious Observers said in the video. The solar maximum is building now, and Earth's magnetic…

Major farside solar activity – July 15 – 17, 2021

Major farside solar activity – July 15 – 17, 2021

Major solar activity is taking place on the 'farside' of the Sun with a number of large-scale coronal mass ejections (CMEs) from July 15 through 17. This should continue in the coming week. Video courtesy: SolarWatcher Featured image courtesy: STEREO-A…

Major X1.5 solar flare erupts — the first X-class flare of Solar Cycle 25

Major X1.5 solar flare erupts — the first X-class flare of Solar Cycle 25

A major solar flare measuring X1.5 at its peak erupted on the Sun's NW limb — most likely from the newly-formed Active Region 2838 — on July 3, 2021, producing R3 – Strong radio blackout. The event started at 14:18, peaked at 14:29, and ended at 14:34 UTC….
