An Entire Year Of Sunspots

This is sunspot dedication. Every day in 2025 (clouds permitting), Warren Spreng of Mason, Ohio, pointed his filtered Seestar 50 telescope at the sun and took a picture. "I then layered each day's image over the previous day's to build a composite of the disk with all the sunspots for that month," Spreng explains.

This is the result. Click on the image for a high-res view of every sunspot in 2025:

Spreng's archive shows at a glance that Solar Cycle 25 is far from over. Every month in 2025 brought numerous large sunspots on both sides of the sun's equator. As 2026 begins, the monthly-averaged sunspot number remains comfortably above 100.

Solar cycle predictions from NOAA suggest that the sunspot number should remain about this high throughout most of 2026 with a slow decline toward Solar Minimum underway by the end of the year. Between now and then, space weather will continue to storm.
