A moderately strong solar flare measuring M1.1 erupted at 07:24 UTC on May 29, 2020. This is the first M-class solar flare of the new solar cycle — Solar Cycle 25. The event started at 07:13, peaked at 07:24, and ended at 07:28 UTC. The eruption took place on the…
Solar activity is at very low levels and the visible disk remains spotless for the 17th day in a row, making a total of 33 days in 2020 or 66 percent — we are still in a Solar Minimum, which is expected to end sometime this year. As a result of weakened Sun's…
After 40 days with no sunspots on the Earth-facing side of the Sun, a new sunspot emerged near the southeast limb of the Sun on December 23, 2019, and was numbered Active Region 2753 on December 24. The region has magnetic polarity -/+, opposite of +/- magnetic…
The solar wind environment is expected to become enhanced and disturbed later on September 27, 2019 (UTC). G1 – Minor Geomagnetic Storm Watch is in effect for September 27, G2 – Moderate for September 28. Quiet to unsettled geomagnetic field conditions are expected…
Solar wind parameters over the past 24 hours were indicative of enhanced solar wind environment, likely caused by a combination of a glancing blow from a slow-moving Coronal Mass Ejection and influences of a negative polarity CH HSS. Total IMF strength was at 5 to 6…
Our planet has entered a stream of fast-moving solar wind flowing from a large positive polarity coronal hole. A G1 – Minor Geomagnetic Storm Watch is in effect for August 31 and G2 – Moderate for September 1. Solar wind parameters reflected a slow regime through…
A several degree long solar filament south of the Region 2741 disappeared by approximately 15:14 UTC on May 13, 2019. Initial analysis suggests an Earth-directed component is likely with this Coronal Mass Ejection (CME). This is the fifth Earth-directed CME since…
An asymmetric full halo CME with a likely Earth-directed component erupted May 6, 2019. The source is still unknown, it is possible this was another stealth CME. Sun's northeastern limb continued exhibiting increased CME activity on May 6 and 7, 2019. This…
A moderately strong solar flare measuring C9.9 erupted from AR 2740 (Beta-Delta) at 05:10 UTC on May 6, 2019. The event started at 05:04 UTC and ended at 05:12 UTC. This is the strongest solar flare since M1.0 at 23:28 UTC on October 20, 2017. A Type II Radio…
An impulsive solar flare measuring C5.6 at its peak time erupted from AR 2736, the source of yesterday's C4.8 and associated asymmetric full-halo CME, at 03:12 UTC on March 21, 2019. The event started at 03:08 and ended at 03:15 UTC. There were no radio…
