A moderately strong solar flare measuring M4.4 at its peak erupted at 13:11 UTC on November 29, 2020, from a region about to rotate into Earth view. The event started at 12:34 and ended at 13:41 UTC. This is the strongest solar flare in more than 3 years. A Type II…
Although solar activity remains at low levels, Active Region 2786 — the biggest sunspot in years — has produced multiple C- and B-class flares since November 25. Coronal Mass Ejections (CMEs) were also observed, but none was Earth-directed. While we are still…
A Coronal Mass Ejection (CME) produced by a C4.3 flare at 06:16 UTC on October 27, 2020, was analyzed by the SWPC and determined to be a possible glancing blow on November 1. The source of the flare was a large AR 2778 which produced multiple B- and C-class flares…
A weak solar flare measuring B1.2 at its peak erupted on August 16, 2020, producing a coronal mass ejection (CME). Consensus model results suggest an arriving glancing blow on August 20 — producing unsettled to active geomagnetic field conditions, with a chance for…
A new study published in the Nature Scientific Reports on July 13 suggests that powerful eruptions on the Sun can trigger large earthquakes on Earth. In the paper, the authors analyzed 20 years of proton density and velocity data, as recorded by the SOHO satellite,…
Our Sun launched two solar storms this week, one of which was Earth-directed, Space Weather Physicist Dr. Tamitha Skov reports in her latest space weather forecast released July 14, 2020. The storm has hit, right on time, and all through the night people have been…
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…
