Grid NM91 Band Conditions
Localized HF conditions for Maidenhead locator NM91. Coordinating at 31.50°, 99.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
NM91 conditions are POOR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 105.
From the NM91 operating area, work the 23:13 UTC and 11:23 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses NM91.
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 NM91 — the NM91 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from NM91 to each DX region at SFI 105 / Kp 1.33, 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 NM91
A planning heuristic for the local day at NM91, built from sunrise 23:13 UTC, sunset 11:23 UTC, SFI 105, and Kp 1.33. 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.
Modest SFI — 20m is the daytime workhorse here.
20m and 15m carry the daytime load at this SFI.
Second grayline peak — 20m holds, then hands off to 40m.
Low bands own the darkness — 40m for DX, 80m regional.
