Grid CO54 Band Conditions — Canada
Localized HF conditions for Maidenhead locator CO54. Coordinating at 54.50°, -129.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
CO54 conditions are POOR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 105.
From Canada operating area, work the 14:21 UTC and 02:39 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses CO54.
After sunset, 20m transitions and 40m becomes the reliable DX fallback from this part of North America.
This square sits in Canada footprint and is best used as a planning center for portable, field-day, and home-station band decisions.

● Best DX Windows from CO54 — Canada operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from CO54 to each DX region at SFI 105 / Kp 2, 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 CO54
A planning heuristic for the local day at CO54, built from sunrise 14:21 UTC, sunset 02:39 UTC, SFI 105, and Kp 2. 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.
Modest SFI — 20m is the daytime workhorse here.
20m and 15m carry the daytime load at this SFI.
Second grayline peak — 20m holds, then hands off to 40m.
Low bands own the darkness — 40m for DX, 80m regional.
