The monthly sunspot number just hit a 23-year high. The last time sunspots were this numerous, the sun was on the verge of unleashing the Great Halloween Storms, which included the strongest X-ray solar flare ever recorded (X45) and a CME so powerful it was detected by the Voyager spacecraft at the edge of the solar system.
Solar Cycle 25 wasn’t expected to be this strong. When it began in Dec. 2019, experts predicted it would be a weak cycle like its immediate predecessor Solar Cycle 24. If that forecast had panned out, Solar Cycle 25 would be one of the weakest solar cycles in a century.
Instead, Solar Cycle 25 has shot past Solar Cycle 24 and may be on pace to rival some of the stronger cycles of the 20th century. Already in May 2024 we have experienced a century-class geomagnetic storm with auroras sighted in the South Pacific, central America and south Africa.The last time sunspot numbers were this high, the sun was on the verge of launching the Great Halloween Storms of 2003, which included the strongest X-ray solar flare ever recorded (X45) and a CME so powerful it was ultimately detected by the Voyager spacecraft at the edge of the solar system.
Is this Solar Max? The jury is still out. Sunspot numbers may continue to rise in the months ahead and, based on the behavior of previous cycles, we can confidently expect high solar activity for at least 2 to 3 more years. Stay tuned! Solar flare alerts: SMS Text
