Along with the April 8 total solar eclipse and vibrant displays of auroras, there’s one other celestial deal with for skywatchers this yr: the primary “main lunar standstill” since 2006. Throughout this occasion, the moon rises and units at its most excessive northerly and southerly positions on the horizon, reaching its highest and lowest factors within the 18.6-year lunar cycle.
That is attainable as a result of the moon does not comply with the identical path as the sun. Its rising and setting positions on the horizon change continuously as a result of actions of Earth and the moon. The solar system is flat, with the planets orbiting the solar on the identical aircraft, often known as the ecliptic. Earth rotates on an axis tilted by 23.4 levels with respect to this ecliptic, inflicting the solar to rise and set inside virtually 47 levels — a spread it step by step covers over a complete yr. The moon’s orbit is tilted by 5.1 levels relative to the ecliptic, permitting it to rise and set inside a 57-degree vary in any given month.
This explains why the moon can generally rise and set at factors on the horizon farther north and south than the solar can.
A significant lunar standstill, or lunistice, happens when the tilts of each Earth and the moon are at their most. Throughout this era, the moon rises and units on the extremes of its vary. It rises at its very highest northeasterly level and units at its very highest northwesterly level. Throughout this era, it additionally rises at its most southeasterly level and units at its most southwesterly level.
The main lunar standstill considerably impacts how lengthy the moon is within the sky at night time. A moon rising farthest northeast within the Northern Hemisphere climbs greater into the sky and stays within the sky longer. It shines in a noticeably totally different place than throughout a minor lunar standstill, when the vary of the place it rises and units is at its narrowest. Historic websites reminiscent of Stonehenge, Callanish and Newgrange appear to be aligned with moonrise and moonset factors throughout a serious lunar standstill, indicating the celestial occasion’s previous significance.

This main lunar standstill can be at its most excessive across the equinoxes in September 2024 and March 2025. Nevertheless, visibility depends upon the moon’s phase, your location and the climate. Good occasions to look embody when the moon rises and the solar units, and vice versa, throughout a full moon.
On June 21, the solar will rise and set at its most northeasterly and northwesterly factors, whereas the total Strawberry Moon will rise and set at its most northeasterly and northwesterly factors. Conversely, on Dec. 15, the solar will rise and set at its most southeasterly and southwesterly factors, whereas the total Chilly Moon will rise and set at its most northwesterly and northeasterly factors.
To look at these phenomena, watch from precisely the identical location, and you will discover a giant distinction. A pair of stargazing binoculars or a good backyard telescope aren’t crucial to note the impact, however they could assist you to zoom in on Earth’s fully-illuminated satellite tv for pc to get essentially the most out of your lunar skywatching.
