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…
A solar filament eruption took place shortly before 12:00 UTC on February 20, 2021, producing a partial-halo CME. Analysis suggests a glancing blow from the periphery of the CME is likely on February 23 or 24. The CME signature was first observed in SOHO/LASCO C2…
Unsettled to active geomagnetic field levels are possible on January 5, 2021, due to the onset of an anticipated Solar Sector Boundary Crossing (SSBC) followed by coronal hole influence late in the day. G1 – Minor geomagnetic storm conditions are likely on January 6…
A long-duration solar flare measuring C7.4 at its peak erupted from Active Region 2790 — positioned in Earth-striking zone — at 16:32 UTC on December 7, 2020. The event started at 15:46, peaked at 16:32, and ended at 17:33 UTC. An asymmetric full halo coronal mass…
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…
