Moon phase today: What the Moon will look like on September 20, 2026

As of September 20, 2026, the Moon is currently in the Waxing Gibbous phase, with 64% of its surface visible, according to NASA's Daily Moon Guide tracker. This phase will continue to progress until the next Full Moon, which is expected to occur on September 26, 2026. During this time, several prominent lunar features will be visible without the aid of visual aids.

These include the Mare Vaporum, Mare Serenitatis, the Tycho Crater, the Alphonsus Crater, the Posidonius Crater, and the Apennine Mountains. For those with access to a telescope, the Apollo 11, 16 and 17 landing spots will also be visible. The Moon's appearance changes nightly as it orbits Earth, revealing different portions of its illuminated side, which creates the lunar phases.

These phases range from a New Moon, when the Moon is between Earth and the Sun and thus invisible to the naked eye, to a Full Moon, when the entire face of the Moon is illuminated and fully visible.

600 Terms, a Degree-14 Rational Generating Function, and a Limit Near π

I have been working on a deterministic operator called (EOA). It maps the spoken names of letters into integer sequences. For one English encoding, I generated over 600 terms of one sequence.

  • Researchers generated over 600 terms of a sequence using EOA
  • gfun tool produced a rational generating function of degree ~14
  • Limit of sequence near π is algebraic, not transcendental
