GET /spaceweather/sunspots
Get recent daily sunspot numbers from NOAA SWPC, tracking solar activity levels. Sunspot numbers correlate with the 11-year solar cycle and predict space weather intensity. Higher sunspot counts mean more frequent solar flares, coronal mass ejections, and aurora displays. Useful for solar cycle tracking dashboards, long-term space weather forecasting, amateur astronomy tools, and climate research applications studying solar irradiance variability.
