● Best DX Windows from MK57 — South Asia operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from MK57 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 MK57
A planning heuristic for the local day at MK57, built from sunrise 01:06 UTC, sunset 13:14 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.
