Storm level needed
Marquette sits at 46.54N 87.40W in Michigan, United States. The IGRF-14 centered dipole puts Marquette at 55.4 degrees geomagnetic latitude, 8.8 degrees closer to the magnetic pole than its map latitude suggests. Marquette sits at 55.4 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 6, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less.
"aurora is commonly visible at high latitudes (northern Michigan and Maine)"
The nearest other Glow towns are Green Bay (230 km), Sault Ste. Marie (234 km), Thunder Bay (247 km). Green Bay sits 2.1 degrees lower on the dipole, Kp 7 against 6 here.
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 Marquette has some civil darkness; the shortest month sample still has 6.8 hours. Every evening of the year at Marquette clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Marquette's longest night of the year, Dec 18, has 14 h 10 min of civil night.
Solar midnight at Marquette, when the sun is lowest, falls at 00:45 on local clocks on December 15 and 01:50 on June 15. That is 45 min after midnight in December and 1 h 50 min after midnight in June, the gap set by daylight saving and the equation of time. So at Marquette the darkest hour sits late in SWPC's 10 PM to 2 AM window.

By the 15th-of-the-month sample, December is the darkest month at Marquette with 14.1 hours of civil night and June the lightest at 6.8. Across the year Marquette gets 3,848 hours of civil night. Astronomical night at Marquette, the sun 18 degrees or more below the horizon, lasts 11.7 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Marquette at 76% across the year, from 68% in August to 81% in January. In the months with at least 4 hours of civil night Marquette averages 76%, against a median of 61% for Glow towns in United States.
Multiplying civil night by the clear share of the sky gives September the best score, 3.3 hours, ahead of October at 2.9. Marquette's equinox months score 2.9 in March and 3.3 in September, the weeks SWPC links with larger storms.
Kp history
From 1996 to 2025, the GFZ Potsdam record shows a 3-hour Kp of 6 or more, the level that puts the average oval edge over Marquette, on 3% of days. At Marquette's level the share runs from 1% in December to 5% in October, while storm days with Kp 5 or more made up 10%.

Moon, next 30 nights
Over the 30 nights from Oct 1, the new moon falls on Oct 10 and the full moon on Oct 26, in America/Detroit dates. 15 of the 30 nights at Marquette have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 5 has the most at 4 h. Tonight Marquette has 11 h 15 min of civil night, 2 h 5 min of it with the moon down.
