On Monday, October 12, 2026, the moon continues in its new phase, with only 2% to 5% of its disk illuminated. The satellite positions itself between the Earth and the Sun, causing its illuminated face to be turned away from our planet. This configuration makes it almost invisible in the night sky, appearing only very close to the horizon shortly after sunset.

What the New Moon Phase Represents

The new moon phase marks the beginning of a new 29.5-day lunar cycle, energetically associated with planting new intentions, organizing plans, and focusing on self-care. It is the ideal time to sow new projects and align goals.

Visibility and Night Observation

With the moon almost invisible, the sky becomes an ideal stage for observing stars, planets, and constellations. The absence of lunar brightness reduces glare and highlights celestial bodies against the cosmic background.

Impact of Weather on Observation

Air quality influences astronomical visibility. Rising global temperatures have altered the rain cycle, intensified drought periods, and favored the accumulation of wildfires. The smoke and soot generated remain suspended in the air, creating a dry haze that can hide stars and impair visibility.

October 2026 Lunar Calendar

  • 10/03 – Waning Crescent (at 10:25 AM)
  • 10/10 – New Moon (at 12:50 PM)
  • 10/18 – Waxing Crescent (at 01:12 PM)
  • 10/26 – Full Moon (at 01:11 AM)

Next Steps in the Waxing Phase

After the new moon, the waxing crescent phase emerges on October 18. Gradually, a small illuminated sliver begins to appear, growing night after night until it reaches the first quarter. This period symbolizes growth, development, and the forging of new paths.
