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...

New data provided by the students of Earth to Sky Calculus and Dr. Tony Phillips of SpaceWeather.com show that cosmic radiation levels in the Earth's atmosphere are decreasing as the new solar cycle -- Solar Cycle 25 -- gains strength. The plot below shows...

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....

A moderately strong solar flare measuring M2.7 at its peak erupted from the newly-formed Active Region 2838 on July 3, 2021. The event started at 07:04 UTC, peaked at 07:17, and ended at 07:22. The position of this region does not favor Earth-directed coronal mass...

A small part of coronal mass ejection (CME) produced by a long-duration C-class solar flare on May 28 hit Earth on June 2, 2021, barely disturbing Earth's magnetic field. Solar wind parameters are likely to become slightly enhanced due to the influence of a...

A long-duration C9.4 solar flare erupted from Active Region 2824 at 23:13 UTC on May 28, 2021, producing a strong coronal mass ejection (CME) and S1 - Minor proton radiation storm. The flare event was associated with Type II Radio Emission with an estimated velocity...

Solar activity has increased from low to moderate levels on Saturday and Sunday, May 22 and 23, 2021, with a series of C- and M-class solar flares produced by Active Region 2824. Multiple CMEs were produced during this period, with several having Earth-directed...

NOAA SWPC forecasters have issued a geomagnetic storm watch for May 18, 2021, after a pair of coronal mass ejections (CMEs) launched from the Sun on May 13 and 14. Enhanced solar wind parameters are expected on May 17 due to the influence of a negative polarity...

A coronal mass ejection (CME) produced by a filament eruption around 10:00 UTC on May 9, 2021, has reached Earth at 06:43 UTC on May 12. G3 - Moderate geomagnetic storm levels were observed at 12:59 UTC. The CME arrived at the DSCOVR spacecraft at 05:47 UTC. Solar...
May 12, 2021
Two coronal mass ejections (CMEs) with Earth-directed components were produced on the Sun on May 9, 2021. The impact is expected early Wednesday, May 12. Active Region 2833 produced a long-duration C-class solar flare measuring C4.0 at its peak at 14:49 UTC on May 9...
May 10, 2021
A strong solar flare measuring M3.9 at its peak erupted from Active Region 2822 at 19:04 UTC on May 7, 2021. While this is one of the strongest solar flares of the new solar cycle -- SC25, the location of region 2822 does not favor Earth-directed CMEs. This event...

A partial halo Coronal Mass Ejection (CME) produced by the C3.8 solar flare from Region 2816 at 04:35 UTC on April 22 is heading toward Earth and is expected to arrive on April 25. As a result, a G2 - Moderate geomagnetic storming is expected. This CME has been...
April 24, 2021
A C3.8 solar flare erupted from Active Region 2816 at 04:35 UTC on April 22, 2021, producing a coronal mass ejection (CME). The event started at 04:10 and ended at 05:00 UTC. The location of the source region favors Earth-directed CMEs. The flare was associated with...
April 22, 2021
A moderately strong solar flare measuring M1.1 at its peak erupted at 23:42 UTC on April 19, 2021. The event started at 23:19 and ended at 23:59 UTC. The source was Active Region 2816 (beta). Associated with this event were Type II (shock velocity of 750 km/s) and...
April 20, 2021
Solar wind parameters over the past 12 hours indicated the arrival of a slow-moving Coronal Mass Ejection (CME), likely produced on April 10. A period of G1 - Minor storming began at 08:59 UTC on April 15. Another enhancement in parameters is expected on April 16...
