New Moon, September 2026
11 Sep 2026, 03:27 UTC · Sun and Moon at 18.4° Virgo · not an eclipse
The New Moon of September 2026 is exact 11 Sep 2026, 03:27 UTC, Sun and Moon conjunct at 18.4° Virgo. It is not an eclipse — the conjunction is 19.7° from the nodes, outside the limit — and the first lunation since the two eclipses of August. In the 19 hours before it, Venus enters Scorpio (10 Sep 2026, 08:06 UTC), Mercury enters Libra (10 Sep 2026, 16:20 UTC), Uranus stations retrograde at 5.6° Gemini (10 Sep 2026, 21:00 UTC). That is 10 Sep, 23:27 EDT in New York, 11 Sept, 04:27 BST in London and 11 Sept, 13:27 AEST in Sydney.
17 days — to exact, counted from 2026-08-25 02:47 UTC; the Moon is waxing gibbous at 90.9% illumination now.

What this means for everyone
An ordinary new moon, and why that matters
A new moon is the instant the Moon's longitude catches the Sun's — found here as the root of their separation on an hourly Swiss Ephemeris lattice. This one is not an eclipse: the conjunction sits 19.7° from the lunar nodes, far outside the limit. After a month with two eclipses, that is the fact worth stating first. The eclipse season closed with the partial lunar eclipse of 28 Aug 2026; the cycle returns to its plain rhythm here, and the next eclipse of any kind is 6 Feb 2027.
18.4° Virgo, and a sky changing gear
The conjunction is at 18.4° Virgo, in the second decan of a mutable sign — the degree the tradition reads as sorting, mending and making useful, the seed of a month spent on method. That reading is collective and it is the same for every chart. What gives this particular new moon its texture is the day before it: Venus enters Scorpio at 08:06 UTC on 10 Sep 2026; Mercury enters Libra at 16:20 UTC on 10 Sep 2026; Uranus stations retrograde at 5.6° Gemini at 21:00 UTC on 10 Sep 2026 — 3 events in about 19 hours. A new moon that follows two sign changes and a station opens a month in which several planets have just changed register.
The days after
The Sun and Moon separate quickly, and the first exact aspects of the new month come within two days: Mercury trine Pluto 12 Sep 2026, 15:59 UTC, and Mercury opposition Neptune 12 Sep 2026, 16:37 UTC. Mercury, freshly in Libra, makes both. They are planet-to-planet contacts — the sky's own aspects, the same for everyone — and they are listed so the month has a shape rather than a single date.
The same degree, a different chart
Eighteen degrees of Virgo is eighteen degrees of Virgo everywhere, and the month it opens is the same month for everyone; the tradition's reading of a Virgo new moon — method, repair, the useful over the grand — is a collective one. Whether it meets a natal point is a question of degrees on the mutable cross — a planet or angle near 18.4° of Gemini, Virgo, Sagittarius or Pisces takes an exact aspect from this new moon — and which house it seeds is a question of birth time and place. The handoff below carries both questions to the chart.
What the instrument claims
An instant, a degree, an eclipse verdict, and the dated context around it. It does not read the month for anyone, and it does not treat a Virgo new moon as advice.
For your chart specifically
The new moon is at 18.4° Virgo. Its contacts to a chart are exact only for natal points near that degree of a mutable sign; the house it opens needs a birth time.

Common questions
- When is the new moon in September 2026?
- 11 Sep 2026, 03:27 UTC, which is 10 Sep, 23:27 EDT in New York, 11 Sept, 04:27 BST in London and 11 Sept, 13:27 AEST in Sydney. The instant is global; the clock reading is local.
- What sign is the September 2026 new moon in?
- Virgo, at 18.4° Virgo, the Sun and Moon together. That is the tropical degree; a sidereal table has the same instant in Leo.
- Is the September 2026 new moon an eclipse?
- No. It is 19.7° from the lunar nodes; the eclipses of this season were both in August, and the next one is 6 Feb 2027, an annular solar eclipse at 17.6° Aquarius.
- What else happens in the sky that week?
- Venus enters Scorpio, 10 Sep 2026, 08:06 UTC; Mercury enters Libra, 10 Sep 2026, 16:20 UTC; Uranus stations retrograde at 5.6° Gemini, 10 Sep 2026, 21:00 UTC; and the Sun enters Libra 23 Sep 2026, 00:05 UTC.
- When is the full moon after it?
- 26 Sep 2026, 16:49 UTC at 3.6° Aries, not an eclipse. The following new moon is 10 Oct 2026, 15:50 UTC at 17.3° Libra.
- What house does this new moon fall in for me?
- Houses turn with the birth time and place, so a date alone cannot say. Supply both and the app finds the house this new moon seeds for you and lists its contacts to your natal points.
