Tonight's sky above Siem Reap, Siem Reap, Cambodia

Local sky character in Siem Reap

Tropical / equatorial latitudes · northern hemisphere · 18 m elevation

  • The north celestial pole stands 13.4° above the horizon, so stars within 13° of it never set from here.
  • About 61.6% of the whole sky rises above the horizon at some point in the year from this latitude.
  • The Milky Way's core in Sagittarius culminates about 47.6° up, clearing the horizon haze comfortably.
  • The Large Magellanic Cloud only reaches about 6.9° altitude, so it is a low, seasonal target rather than a year-round one.
  • At 18 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.

Best nights this month in Siem Reap

Calculated for these coordinates and today's date — not a fixed list.

  • 2026-11-05 — Taurids peak — up to 5/hour

    Radiant in Taurus. Favours the Northern Hemisphere, which includes Siem Reap, Siem Reap, Cambodia. The Moon is 18% lit on peak night, so lunar interference is low.

  • 2026-11-09 — Darkest night of the coming month

    The Moon is only 0% illuminated, giving the least lunar interference in the next 30 nights — the best window for the Milky Way and faint deep-sky targets from Siem Reap, Siem Reap, Cambodia.

  • 2026-11-17 — Leonids peak — up to 15/hour

    Radiant in Leo. Visible from both hemispheres. The Moon is 45% lit on peak night, so lunar interference is moderate.

  • 2026-11-24 — Full Moon

    A 100%-lit Moon washes out faint objects, but lunar terrain along the limb is at its most striking — plan bright targets and planets instead of deep sky.
