Storm level needed
Saint Cloud sits at 45.56N 94.16W in Minnesota, United States. The IGRF-14 centered dipole puts Saint Cloud at 54.0 degrees geomagnetic latitude, 8.5 degrees closer to the magnetic pole than its map latitude suggests. Saint Cloud sits at 54.0 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 6.
"aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.)"
The nearest other Glow towns are West Coon Rapids (78 km), Plymouth (82 km), Minneapolis (95 km). West Coon Rapids sits 0.3 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 Saint Cloud has some civil darkness; the shortest month sample still has 6.9 hours. Every evening of the year at Saint Cloud clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Saint Cloud's longest night of the year, Dec 18, has 14 h 4 min of civil night.
Solar midnight at Saint Cloud, when the sun is lowest, falls at 00:12 on local clocks on December 15 and 01:17 on June 15. That is 12 min after midnight in December and 1 h 17 min after midnight in June, the gap set by daylight saving and the equation of time. So at Saint Cloud the darkest hour sits near the middle of SWPC's 10 PM to 2 AM window in winter.

By the 15th-of-the-month sample, December is the darkest month at Saint Cloud with 14.1 hours of civil night and June the lightest at 6.9. Across the year Saint Cloud gets 3,860 hours of civil night. Astronomical night at Saint Cloud, the sun 18 degrees or more below the horizon, lasts 11.6 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Saint Cloud at 58% across the year, from 46% in July to 68% in December. In the months with at least 4 hours of civil night Saint Cloud averages 58%, against a median of 61% for Glow towns in United States.
Multiplying civil night by the clear share of the sky gives January the best score, 5.5 hours, ahead of September at 5.3. Saint Cloud's equinox months score 4.0 in March and 5.3 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 Saint Cloud, on 3% of days. At Saint Cloud'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 25, in America/Chicago dates. 15 of the 30 nights at Saint Cloud have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 5 has the most at 4 h. Tonight Saint Cloud has 11 h 15 min of civil night, 2 h 12 min of it with the moon down.

- Every night at Saint Cloud has civil darkness. Tonight has 11 h 15 min, and December 15 has 14.1 hours.
- What is the best month for aurora in Saint Cloud?
- January, by civil night at Saint Cloud times the clear share of the sky from NASA POWER's 2001 to 2020 average.
- How cloudy is Saint Cloud in the dark months?
- About 58% mean cloud amount over Saint Cloud in the months with at least 4 hours of civil night, from NASA POWER's 2001 to 2020 all-hours climatology.
