● Best DX Windows from OM89 — Beijing

Great-circle distance, short-path beam heading, the bands most likely open right now from OM89 to each DX region at SFI 104 / Kp 0, 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.

Spots touching OM89 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in OM89, ON80, OM88, OM99, OM79. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate OM89 footprint right now. That usually means you should widen the search to the nearest regional hubs below or fall back to 20m/40m for the next operating window.
