Current Solar Conditions¶
Solar indices sourced from NOAA SWPC (wspr.live_conditions) updated every 15
minutes. SFI is published once daily (~20:00 UTC from Penticton, BC). Kp is
updated every 3 hours.

Current Band Impact Assessment¶
Estimated propagation impact based on current SFI and Kp, derived from measured historical correlations in the IONIS dataset — not modeled predictions.
| Band | SFI Effect | Kp Effect | Net Assessment |
|---|---|---|---|
| 10m (28 MHz) | — | — | — |
| 12m (24.9 MHz) | — | — | — |
| 15m (21 MHz) | — | — | — |
| 17m (18.1 MHz) | — | — | — |
| 20m (14 MHz) | — | — | — |
| 30m (10.1 MHz) | — | — | — |
| 40m (7 MHz) | — | — | — |
| 80m (3.5 MHz) | — | — | — |
| 160m (1.8 MHz) | — | — | — |
Assessment is based on measured SNR correlations across 10.8B WSPR spots and 2.18B RBN spots. Higher bands respond more strongly to SFI. Lower bands are more sensitive to geomagnetic disturbance.
