Grid LO21 Band Conditions — Eastern Europe
Localized HF conditions for Maidenhead locator LO21. Coordinating at 51.50°, 45.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
LO21 conditions are FAIR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 137.
From Eastern Europe operating area, work the 01:09 UTC and 17:05 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses LO21.
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 LO21 — Eastern Europe operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from LO21 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 LO21
A planning heuristic for the local day at LO21, built from sunrise 01:09 UTC, sunset 17:05 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.
