Northern lights in Darwen

Answer

Darwen's OVATION cell reads 0% for 13:20 UTC. It is not civil-dark yet. The next dusk is listed below. OVATION is a model of the next 30 to 90 minutes, not a sighting.

Storm level needed

Darwen sits at 53.70N 2.46W in England, United Kingdom. The IGRF-14 centered dipole puts Darwen at 55.8 degrees geomagnetic latitude, 2.1 degrees closer to the magnetic pole than its map latitude suggests. Darwen sits at 55.8 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)"

NOAA SWPC, G1 Minor, Kp = 5

The nearest other Glow towns are Bolton (13 km), Preston (17 km), Burnley (19 km). Bolton 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

Civil twilightNautical twilightAstronomical nightMoon up in darkness10 PM to 2 AM, SWPC best windowToday

Every night of 2026 at Darwen has some civil darkness; the shortest month sample still has 5.0 hours. Every evening of the year at Darwen clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Darwen's longest night of the year, Dec 18, has 15 h of civil night.

Solar midnight at Darwen, when the sun is lowest, falls at 00:05 on local clocks on December 15 and 01:10 on June 15. That is 5 min after midnight in December and 1 h 10 min after midnight in June, the gap set by daylight saving and the equation of time. So at Darwen 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 Darwen with 15.0 hours of civil night and June the lightest at 5.0. Across the year Darwen gets 3,725 hours of civil night. Astronomical night at Darwen, the sun 18 degrees or more below the horizon, lasts 12.0 hours on December 15.

NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Darwen at 77% across the year, from 72% in May to 82% in January. In the months with at least 4 hours of civil night Darwen 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, 2.7 hours, ahead of February at 2.7. Darwen'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 6 or more, the level that puts the average oval edge over Darwen, on 3% of days. At Darwen'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 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 Darwen have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 6 has the most at 4 h. Tonight Darwen has 11 h 15 min of civil night, 2 h 4 min of it with the moon down.
