Upcoming sky events from San Luis

14 December

Geminid meteor shower

Widely considered the best shower of the year: slow, bright, often colourful meteors at up to ~150 per hour under dark skies. In 2026 the Moon is only a young crescent at the 13–14 December peak, so conditions are excellent.

21 October · lesser-known

Orionid meteor shower

Fast, faint meteors — debris from Halley's Comet — peaking around 21 October at ~20 per hour. A quieter, connoisseur's shower; moonlight hampers the 2026 peak, so aim for the darkest hours.

17 November · lesser-known

Leonid meteor shower

The Leonids peak around 17 November at ~15 fast meteors an hour. Famous for rare, spectacular storms every ~33 years; 2026 is a normal year, but still a pleasant pre-dawn watch.

23 December

December supermoon

The final and closest supermoon of 2026 on 23 December — a full Moon near its closest approach to Earth, appearing slightly larger and noticeably brighter. Lovely to the eye, especially rising near the horizon.
