Today, Earth-orbiting satellites detected the biggest solar flare in more than 3 years. The M4.4-category eruption produced a shortwave radio blackout over some parts of Earth and a bright coronal mass ejection (CME). Remarkably, the flare was even bigger than it seemed. The blast site is located just behind the sun’s southeastern limb, so the […] Read more

Solar Flux Hits New High & Big Flares Possible Now | Space Weather News 11.26.2020 Read more

Tad Cook, K7RA, Seattle, reports: As solar flux declined over the past week, I noticed less long-distance propagation on 10 meters reported on pskreporter.info from my local grid square, CN87. Propagation on 12 meters was quite strong, however. After 0100 UTC on November 15, transequatorial propagation was evident between East Asia and Australia on 10 meters.  Solar […] Read more

Tad Cook, K7RA, Seattle, reports: The last time we experienced a day with no sunspots was October 13. Prior to that, September 26 – October 8, September 24, and August 21 – September 22 had no sunspots. Cycle 25 is clearly under way and going strong. Average daily sunspot number over the November 5 – […] Read more

Sunspot region 2782 which is located near the south-east limb produced a long duration C2.6 solar flare which peaked today at 19:11 UTC. C-class solar flares aren’t the strongest solar flares out there but its long duration caught our attention as long duration solar flares are often associated with the release of a plasma cloud […] Read more

Tad Cook, K7RA, Seattle, reports: The 10.7-centimeter solar flux density was 88.1 on Wednesday, November 4, the highest since October 14, 2016, when it was 92.8. The average daily solar flux for that week as reported in this bulletin was 76.9, and average daily sunspot number was 18.7, so activity 4 years ago was similar to recent […] Read more

Tad Cook, K7RA, Seattle, reports: Our sun is finally waking up. The average daily sunspot number rose this week from 15 to 17, which is nothing remarkable, but the reporting week ended on Wednesday with a daily sunspot number of 36. Average daily solar flux rose from 74.5 to 76.9. The two sunspot regions currently […] Read more

This week our Sun continues its upward climb in activity with multiple new bright regions on the Earth-facing disk, including a new sunspot region (region 2778). On top of this we finally had that massive snake-like filament that we first saw in STEREO-A’s view on the far side of the Sun launch as a non-Earth […] Read more
