Grid DB98 Band Conditions
Localized HF conditions for Maidenhead locator DB98. Coordinating at -71.50°, -101.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
DB98 currently has elevated aurora risk (Kp: 5). High-latitude paths may be degraded.
From the DB98 operating area, work the no sunrise — polar night and no sunset — polar night grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses DB98.
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 DB98 — the DB98 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from DB98 to each DX region at SFI 150 / Kp 5, 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 DB98
A planning heuristic for the local day at DB98, built from sunrise no sunrise — polar night, sunset no sunset — polar night, SFI 150, and Kp 5. 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. Geomagnetic storm in progress (Kp 5) — expect absorption and weak high-latitude paths.
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. Geomagnetic storm in progress (Kp 5) — expect absorption and weak high-latitude paths.
Low bands own the darkness — 40m for DX, 80m regional. Geomagnetic storm in progress (Kp 5) — expect absorption and weak high-latitude paths.
