Storm level needed
Vancouver, Washington sits at 45.64N 122.66W in Washington, United States. The IGRF-14 centered dipole puts Vancouver, Washington at 51.1 degrees geomagnetic latitude, 5.4 degrees closer to the magnetic pole than its map latitude suggests. Vancouver, Washington sits at 51.1 degrees geomagnetic. The lowest NOAA storm level whose typical viewing latitude reaches it is G3 (Kp = 7). By SWPC's rule the average oval edge is overhead only at Kp 8.
"aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.)"
The nearest other Glow towns are Portland, Oregon (13 km), Gresham (24 km), Hillsboro (29 km). Portland, Oregon sits 0.1 degrees lower on the dipole and needs the same Kp.
Approximate: SWPC calls its Kp to latitude rule an average, and a centered dipole can differ by a degree from fuller field models. How the storm level is matched
The year in darkness
Every night of 2026 at Vancouver, Washington has some civil darkness; the shortest month sample still has 6.9 hours. Every evening of the year at Vancouver, Washington clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Vancouver, Washington's longest night of the year, Dec 16, has 14 h 4 min of civil night.
Solar midnight at Vancouver, Washington, when the sun is lowest, falls at 00:06 on local clocks on December 15 and 01:11 on June 15. That is 6 min after midnight in December and 1 h 11 min after midnight in June, the gap set by daylight saving and the equation of time. So at Vancouver, Washington the darkest hour sits near the middle of SWPC's 10 PM to 2 AM window in winter.
