Grid NP42 Band Conditions
Localized HF conditions for Maidenhead locator NP42. Coordinating at 62.50°, 89.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
NP42 conditions are FAIR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 137.
From the NP42 operating area, work the 20:58 UTC and 15:24 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses NP42.
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 NP42 — the NP42 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from NP42 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 NP42
A planning heuristic for the local day at NP42, built from sunrise 20:58 UTC, sunset 15:24 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.
