Uranus–Neptune crossing

What the Uranus–Neptune crossing means

Uranus and Neptune move so slowly that everyone born in the same few weeks has them in nearly the same places in the sky, so a whole birth cohort shares nearly the same paran latitudes for this pair. The crossing points still differ from one person to the next, because they depend on the birth moment. Uranus caught up with Neptune in 1993, and for people born in the years around it the two planets sat so close that their lines run almost together: the MC lines within a few degrees of longitude through the early 1990s and almost touching in 1993, the rising and setting lines in close company across most of the map.

For that cohort the pair works less as a crossing than as one doubled line. The parans with one planet on the meridian sit at about 67° to 69° north and south, along the Arctic and Antarctic circles, where few people live. The latitude where both rise together is the exception to the slow-pair rule: while the planets are this close it shifts by many degrees within weeks, which makes it the least reliable paran of the set.

The tradition reads Uranus with Neptune as ideals and imagination meeting the urge to break with the past: art made with new tools, unconventional beliefs, the pull of communities that live differently. That describes a generation more than a person. What makes it yours is whether either planet touches your Sun, Moon, Mercury, Venus or an angle at birth, and which personal lines run near the doubled line on your map. A Mercury line beside it is read as ideas and technology, a Venus line as art and unusual love, a Moon line as a dreamy, unsettled home.

Where they meet on your map

Your Uranus MC and IC lines run from pole to pole, and so do your Neptune ones, so those four never meet. Each of them crosses the other planet's rising and setting curve once, which makes up to four crossings of a meridian line with a horizon line, and the rising and setting curves of the two can cross each other as well. Where they fall depends on the moment you were born: every chart has them, though some land in the middle of an ocean or too near a pole to be drawn.

At a crossing both planets were on angles in the same place at the same moment. Move east or west along that latitude and the same two still reach their angles together, only at another time of day, so astrocartography reads the whole latitude as a Uranus–Neptune paran. Zenith Map draws it as a band 1° (about 110 km) either side, and its weight in a place's score fades with distance from the latitude.

Birth time

A wrong birth time moves every line, and the crossings with them: an hour's error puts each crossing 15° of longitude east or west, more than 1,600 km at the equator. The paran latitude hardly moves, because it depends on where the two planets were in the sky rather than on the time of day; in the engine's test charts an hour shifts it by about a tenth of a degree or less nine times out of ten. With an uncertain birth time, trust the paran before the crossing. What a doubtful birth time does to a map.
