Jennifer Lopez's Birth Chart

The Moon ran from 22°13′ Scorpio to 6°29′ Sagittarius, crossing the sign line at 1:10:23 PM, so Scorpio had it for the first 13 hours 10 minutes. Scorpio is the Moon's fall in classical dignity tables; Sagittarius carries no such mark. A same-day sign change marks about 44% of 1960s births. The hour also decides whether the Moon was out of bounds: inside the limit at the opening midnight, beyond it by midday.

Any sign could be Lopez's Ascendant. Over the Bronx the horizon changed sign twelve times, Taurus rising at both ends; Leo and Scorpio each held for 2 hours 32 minutes, Pisces and Aries for 1 hour 11 minutes. Leo was already rising when the Sun came up at 5:44 AM, and Astrotheme's noon falls in the Libra span, 10:46 AM to 1:18 PM. Houses turn with that horizon and sect with the Sun's height, so neither can be assigned.

Ordered by importance times infrequency in a simulated 1960s sample: the Sun in its own sign (about one chart in 12), Mercury combust (about one chart in 4), Mars out of bounds (about one chart in 5), a locomotive shape (about one chart in 11), a first quarter Moon (about one chart in 8) and a Moon that changed sign (about 44%).

Over the date the Sun advanced from 1°04′ to 2°02′ in Leo, the sign it rules in the scheme of essential dignities; older authors let a planet at home act on its own terms. Mercury, fast and pulling ahead, widened its lead on the Sun from 1°48′ to 2°56′: combust all day, never near enough for cazimi. Medieval authors treated a planet that deep in the Sun's rays as scorched and muted.

Mars hardly moved, 0°12′ in the whole date, and its declination lay past the Sun's 23°26′ limit; writers on declination read such a planet as working outside ordinary rules. The Moon held its first quarter phase throughout, and in the table only Neptune and Chiron ran retrograde.

Of the 15 aspects in orb all day, a single cluster hangs on the Sun–Mars trine: Jupiter and Uranus, conjunct in early Libra, sit sextile to both ends, the figure some modern textbooks name a minor grand trine, and Mercury, beside the Sun, repeats each contact. Sun sextile Jupiter and Mercury trine Mars both perfected during the date. The Moon's contacts depend on the hour: conjunct Mars from 3:45 AM, conjunct Neptune until 7:30 PM.

The planets fill 205°12′ from Saturn in Taurus onward and leave Capricorn through Aries bare, the spread Marc Edmund Jones called a locomotive and linked with drive; the gap here is wider than his third of a wheel yet short of a bowl's half, and the shape appears in about one chart in 11 from the decade. Without the Moon, fire and air hold three planets each, Neptune alone is water and fixed signs lead with four; a Sagittarius Moon would put fire ahead, a Scorpio Moon would give water a second.

Satya Nadella's chart scores closest, then Christopher Nolan's, Bill Clinton's and Barack Obama's. All four share the Leo Sun, and Obama's adds a Mercury pairing, listed as “Mercury within 2° of each other”. Nobody else in the databank shares the birth date.

With Lahiri's 23°25′ correction taken off, the Sun and Mercury slip back into Cancer, Venus into Taurus, Mars into Scorpio, and Jupiter and Uranus into Virgo; Jyotish counts the Venus and Mars placements as own-sign. The sidereal Moon leaves Libra for Scorpio roughly two hours after midnight, giving a Scorpio Moon for almost any hour.

Saturn regained its noon position, 8°17′ Taurus, for the first time on May 9, 1999, a one-pass return at age 29.8. Jupiter's first return came in three passes, the middle one retrograde; the latest, on September 15, 2016, was a single crossing.

Positions are computed by precise astronomical calculations at both midnights of the date for 40°50′ N, 73°52′ W, the Bronx, where daylight time ran from April 27 to October 26, 1969. All-day aspects held at every sample, taken every 10 minutes of the local date; rates come from simulated 1960s births, as the about page explains.
