The Equinox Approaches

Across the northern hemisphere, mid-September marks the most rapid astronomical transition of the year.

At 41.9 deg N latitude, the sun’s midday elevation has dropped from its summer peak of 71.5 deg down to 49.8 deg above the southern horizon. Day length is shrinking by nearly three minutes each cycle; the point on the horizon where the sun sets is migrating rapidly south toward true West (270 deg), which it will cross exactly on the Autumnal Equinox (September 22).

To live in rhythm with the land is to notice these shifting arcs not as an inconvenience, but as an ancient call to alignment.

The Seasonal Triad: Jera, Kenaz, and Othala

Three staves of the Elder Futhark define the approach to the equinox:

  1. ᛃ Jera (The Completed Cycle): Celebrating the fruits of spring planting. The winter squashes have hardened their rinds, the late peppers hang heavy, and the garden prepares to rest under a carpet of mulch.
  2. ᚲ Kenaz (The Controlled Hearthfire): As ambient outdoor temperatures slip into the 40s, light and fire move indoors. Kenaz is the flame of the woodstove, the reading lamp illuminating deep winter studies, and the focused creative fire that flourishes when outdoor labor subsides.
  3. ᛟ Othala (The Sanctuary Enclosure): The physical preparation of the home. Checking the moisture content of stacked cordwood ($<20\%$), sealing drafty window casings, staging winter emergency power, and ensuring the livestock are warded against northern gales.

Standing Under the Dark Skies

At 1,600 feet elevation under Class 3 rural dark skies, early autumn nights offer an extraordinary celestial panorama.

As soon as astronomical twilight concludes, the Milky Way core arches straight through the zenith like a frosted road of stars, framed by the soaring wings of Cygnus (The Northern Cross).

When you stand beneath that celestial dome, the impending dark of winter carries no threat. It is simply the inward half of the breath. The harvest is gathered; the timber is sound; the hearth is prepared.

Rest in the turning season. Gather the harvest. Kindle the inner fire. ᛃ ᚲ ᛟ
