Last Supermoon of 2025 Rises Over Argentina Tonight

A full Moon at perigee appears slightly larger, with increased brightness.

Overview

  • Skywatchers across much of Argentina are expected to see the event this evening if clouds stay away, with the Moon visible from sunset into the night.
  • Astronomers estimate an apparent diameter about 7% larger than average and brightness roughly 12–15% higher for this perigee full Moon.
  • Observers are advised to look toward the eastern horizon at sunset and seek darker locations with minimal light pollution for clearer views.
  • The Moon’s low altitude in Argentina can produce golden or reddish tones and enhance the lunar-illusion effect, making it seem bigger near the horizon.
  • Local outlets cite National Geographic in reporting that a comparable configuration may not return for about 18 years, with some reports pointing to 2042 for a similar intensity.
