Grid LO66 Band Conditions — Eastern Europe
Localized HF conditions for Maidenhead locator LO66. Coordinating at 56.50°, 53.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
LO66 conditions are FAIR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 137.
From Eastern Europe operating area, work the 00:11 UTC and 16:59 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses LO66.
European evening operation usually shifts toward 20m and 40m once the high bands soften.
This square sits in Eastern Europe footprint and is best used as a planning center for portable, field-day, and home-station band decisions.

● Best DX Windows from LO66 — Eastern Europe operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from LO66 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 LO66
A planning heuristic for the local day at LO66, built from sunrise 00:11 UTC, sunset 16:59 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.
