Upcoming sky events from São João da Boa Vista

28 August

Partial lunar eclipse

A partial lunar eclipse on 28 August, with part of the full Moon dimming and reddening as it enters Earth's shadow. Visible from the Americas, Europe, Africa and Asia depending on your local moonrise/moonset.

4 October

Saturn at opposition

Saturn reaches opposition on 4 October — directly opposite the Sun, so it rises at sunset, sets at sunrise and is at its biggest and brightest of the year. The best night to catch the rings through even a small telescope.

26 September · lesser-known

Neptune at opposition

The most distant planet reaches opposition on 26 September — its brightest for the year, though still faint. A rewarding challenge target: Neptune shows as a tiny blue-grey disc through a telescope. One for the keen.

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.
