On September 15, 2020, NASA confirmed Solar Cycle 25 had officially begun - The solar minimum between Solar Cycle 24 and 25 - the period when the sun is least active - happened in December 2019, when the 13-month smoothed sunspot number fell to 1.8, according to the Solar Cycle 25 Prediction Panel, co-chaired by NOAA and NASA. We are now in Solar Cycle 25 with peak sunspot activity expected in 2025, the panel said.Yesterday, Nov. 8th (0518 UT), our sun became active as giant sunspots AR2781 produced a C5-class solar flare, shown above in a photo from NASA's Solar Dynamics Observatory: A pulse of X-rays and UV radiation ionized the top of Earth's atmosphere, causing a brief shortwave radio blackout over Australia and the Indian Ocean.

Our Sun awakes from a deep slumber: Giant sunspots AR2781 produced a C5-class solar flare kicking off Solar Cycle 25: Solar Cycle 24 had the 4th-smallest intensity since records began in 1755 it was also the weakest cycle in 100 years.

Mariners, aviators, and ham radio operators in the region may have noticed unusual propagation at frequencies below 10 MHz. The entire episode lasted less than 20 minutes. Stronger eruptions are possible. Sunspot AR2781 has a "beta-gamma" magnetic field that harbours energy for M-class flares, 10 times more intense than a C-flare. NOAA forecasters say there is a 15% chance of such an eruption on Nov. 9th. According to Spaceweather.com
