Grid CM59 Band Conditions
Localized HF conditions for Maidenhead locator CM59. Coordinating at 39.50°, -129.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
CM59 conditions are FAIR. Best bands: 10m, 12m, 15m, 17m, 20m. SFI: 137.
From the CM59 operating area, work the 13:27 UTC and 03:59 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses CM59.
10m is the headline band right now, with 20m as the dependable fallback if conditions soften.
This square sits in a mixed-region footprint and is best used as a planning center for portable, field-day, and home-station band decisions.

● Best DX Windows from CM59 — the CM59 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from CM59 to each DX region at SFI 137 / Kp 3, and a current verdict. "Open now" means a suitable band is scoring well on that path; "Try ~HH:MM" points at the next far-end grayline. Band picks and status are a planning heuristic, not a measurement.

● Band-by-Time Plan for CM59
A planning heuristic for the local day at CM59, built from sunrise 13:27 UTC, sunset 03:59 UTC, SFI 137, and Kp 3. Not a measurement — a starting point for where to listen as the day turns.
Grayline enhancement — low bands reach long distances as the terminator passes.
High bands rising with the sun; check 10m for DX.
Peak high-band window — 10m and 15m open widest.
Second grayline peak — 20m holds, then hands off to 40m.
Low bands own the darkness — 40m for DX, 80m regional.
