A geomagnetic sudden impulse — CME produced by a long-duration C7.4 solar flare on December 7, was observed at DSCOVR satellite at the L1 point at 01:32 UTC on December 10. The total field reached 16 nT while wind speeds topped out near 571 km/s, producing a period…
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…
Extremely rare red auroras were seen over Utsjoki, Finland, on Monday and Tuesday, October 12 and 13, 2020. These natural light display, also referred to as northern lights, are normally green. However, for some reason, the solar wind on Monday excited oxygen at…
A recurrent, positive polarity coronal hole high speed stream (CH HSS) is affecting our planet since September 23, sparking active to G1 – Minor geomagnetic storm conditions. A G2 – Moderate geomagnetic storm warning was issued at 08:07 UTC today. In 24 hours to…
Solar minimum occurred in December 2019, marking the start of a new solar cycle, the Solar Cycle 25 Prediction Panel, an international group of experts co-sponsored by NASA and NOAA, announced on September 15, 2020. The solar minimum between Solar Cycle 24 and 25 -…
Our planet is under the influence of a series of coronal holes since August 25, 2020, sparking unsettled to G1 – Minor geomagnetic storm conditions. The effect is expected to continue through at least September 2. G1 – Minor geomagnetic storm threshold was first…
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…
