Grid MA04 Band Conditions
Localized HF conditions for Maidenhead locator MA04. Coordinating at -85.50°, 61.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
MA04 conditions are FAIR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 120.
From the MA04 operating area, work the 00:49 UTC and 14:49 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses MA04.
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 MA04 — the MA04 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from MA04 to each DX region at SFI 120 / Kp 0.67, 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 MA04
A planning heuristic for the local day at MA04, built from sunrise 00:49 UTC, sunset 14:49 UTC, SFI 120, and Kp 0.67. 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.
