Grid BN15 Band Conditions
Localized HF conditions for Maidenhead locator BN15. Coordinating at 45.50°, -157.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
BN15 conditions are FAIR. Best bands: 10m, 12m, 15m, 17m, 20m. SFI: 137.
From the BN15 operating area, work the 15:02 UTC and 06:09 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses BN15.
Night operation should keep 20m on watch and move to 40m as the path darkens.
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 BN15 — the BN15 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from BN15 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 BN15
A planning heuristic for the local day at BN15, built from sunrise 15:02 UTC, sunset 06:09 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.
