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…
A solar flare measuring C4.8 at its peak erupted from newly-emerged AR 2736 on March 20, 2019. The eruption started at 10:35, peaked at 11:18 and ended at 11:34 UTC. The region was also responsible for several B-class flares over the past 7 hours. The flare was…
A long-duration solar flare measuring C1.3 at its peak erupted from Region 2734 (Alpha) at 03:19 UTC on March 8, 2019. The event started at 03:07, peaked at 03:19 and ended at 03:58 UTC. This event was associated with a Type II Radio Emission registered at 03:15 UTC…
A weak solar flare measuring C5.0 at its peak erupted from Active Region 2733 at 13:22 UTC on January 26, 2019. The eruption started at 13:12 and ended at 13:34 UTC. This was the strongest solar flare since February 18, 2018. It was preceded by B1.5 at 03:49 UTC,…
Two plasma filament eruptions were detected on the Sun on July 5, 2018, and it seems at least one weak Earth-directed Coronal Mass Ejection (CME) was produced; ETA July 9 or 10. In addition, a relatively strong farside eruption took place on July 5 and its CME (not…
