Storm level needed
Ripon sits at 54.14N 1.53W in England, United Kingdom. The IGRF-14 centered dipole puts Ripon at 56.1 degrees geomagnetic latitude, 2.0 degrees closer to the magnetic pole than its map latitude suggests. Ripon sits at 56.1 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 5, 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 Harrogate (16 km), Northallerton (23 km), York (35 km). Harrogate sits 0.1 degrees lower on the dipole, Kp 6 against 5 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 Ripon has some civil darkness; the shortest month sample still has 4.8 hours. Every evening of the year at Ripon clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Ripon's longest night of the year, Dec 19, has 15 h 4 min of civil night.
Solar midnight at Ripon, when the sun is lowest, falls at 00:01 on local clocks on December 15 and 01:06 on June 15. That is 1 min after midnight in December and 1 h 6 min after midnight in June, the gap set by daylight saving and the equation of time. So at Ripon 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 Ripon with 15.0 hours of civil night and June the lightest at 4.8. Across the year Ripon gets 3,715 hours of civil night. Astronomical night at Ripon, the sun 18 degrees or more below the horizon, lasts 12.1 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Ripon at 77% across the year, from 74% in May to 79% in January. In the months with at least 4 hours of civil night Ripon averages 77%, against a median of 77% for Glow towns in United Kingdom.
Multiplying civil night by the clear share of the sky gives December the best score, 3.4 hours, ahead of November at 3.1. Ripon's equinox months score 2.6 in March and 2.5 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 5 or more, the level that puts the average oval edge over Ripon, on 10% of days. At Ripon's level the share runs from 5% in December to 14% in September, while storm days with Kp 5 or more made up 10%.

Moon, next 30 nights
Over the 30 nights from Oct 2, the new moon falls on Oct 10 and the full moon on Oct 26, in Europe/London dates. 15 of the 30 nights at Ripon have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 6 has the most at 4 h. Tonight Ripon has 11 h 14 min of civil night, 2 h of it with the moon down.
