Here’s the latest I can see right now and what it means for 11 m:

  • Sunspot number (SSN): about 85

  • Planetary K index (Kp): about 3.7 (call it K = 3–4)

  • Planetary A index (Ap): about 26

What that implies for 11 m (27 MHz)

  • SSN ≈ 85: F-layer DX is very possible, especially along daylight paths. 11 m can open for solid skip, but it’s not at “blowtorch all day” levels; openings may be more directional and time‑dependent.

  • K = 3–4, Ap ≈ 26: That’s unsettled to mildly disturbed geomagnetic conditions. You can still get DX, but:

    • High‑latitude paths can be more fragile or noisy.

    • Signals may be more fluttery and less stable, especially over polar-ish routes.
