📈 Trailing Sunspot Analytics
Real live counts, logged daily on this device — building toward a full 30-day trailing window (day 0 of 30 so far).
Source: real live NOAA SWPC region counts, logged locally on this device each day • Methodology: centered moving average (up to 7-day window) over your own accumulated history — not a pre-loaded historical dataset.

Solar Cycle 25 reached its peak in October 2024 and has been in its declining phase since — 22 months and counting. Strong individual flares can still occur during a decline, as happened in prior cycles years after their own peaks.

Last 7 Days — Peak Flare Class
Real NOAA data, genuinely 7 days (not 30 — that history isn't available from this app's current data sources).
