Grid ML91 Band Conditions — South Asia
Localized HF conditions for Maidenhead locator ML91. Coordinating at 21.50°, 79.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
ML91 conditions are POOR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 105.
From South Asia operating area, work the 00:33 UTC and 12:42 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses ML91.
10m is the first place to check for long-haul openings from this region, with 15m close behind.
This square sits in South Asia footprint and is best used as a planning center for portable, field-day, and home-station band decisions.

● Best DX Windows from ML91 — South Asia operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from ML91 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 ML91
A planning heuristic for the local day at ML91, built from sunrise 00:33 UTC, sunset 12:42 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.
