Grid QR77 Band Conditions
Localized HF conditions for Maidenhead locator QR77. Coordinating at 87.50°, 155.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
QR77 currently has elevated aurora risk (Kp: 5). High-latitude paths may be degraded.
From the QR77 operating area, work the no sunrise — polar day and no sunset — polar day grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses QR77.
10m is the headline band right now, with 20m as the dependable fallback if conditions soften.
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 QR77 — the QR77 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from QR77 to each DX region at SFI 148 / Kp 5, 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 QR77
A planning heuristic for the local day at QR77, built from sunrise no sunrise — polar day, sunset no sunset — polar day, SFI 148, and Kp 5. 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. Geomagnetic storm in progress (Kp 5) — expect absorption and weak high-latitude paths.
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. Geomagnetic storm in progress (Kp 5) — expect absorption and weak high-latitude paths.
Low bands own the darkness — 40m for DX, 80m regional. Geomagnetic storm in progress (Kp 5) — expect absorption and weak high-latitude paths.
