Grid LM56 Band Conditions — Tehran
Localized HF conditions for Maidenhead locator LM56. Coordinating at 36.50°, 51.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
LM56 conditions are FAIR. Best bands: 10m, 12m, 15m, 17m, 20m. SFI: 137.
From Tehran, work the 01:34 UTC and 15:52 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses LM56.
10m and 15m typically deliver the most consistent Europe outbound DX while solar flux remains healthy.
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 LM56 — Tehran
Great-circle distance, short-path beam heading, the bands most likely open right now from LM56 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 LM56
A planning heuristic for the local day at LM56, built from sunrise 01:34 UTC, sunset 15:52 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.
