Grid GA20 Band Conditions
Localized HF conditions for Maidenhead locator GA20. Coordinating at -89.50°, -55.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
GA20 currently has elevated aurora risk (Kp: 4). High-latitude paths may be degraded.
From the GA20 operating area, work the no sunrise — polar night and no sunset — polar night grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses GA20.
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 GA20 — the GA20 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from GA20 to each DX region at SFI 148 / Kp 4, 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 GA20
A planning heuristic for the local day at GA20, built from sunrise no sunrise — polar night, sunset no sunset — polar night, SFI 148, and Kp 4. 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.
