Upcoming sky events from Alcalá de Henares

12 August
Total solar eclipse
The headline event of 2026 and the first total solar eclipse over continental Europe since 1999. The narrow path of totality crosses eastern Greenland, western Iceland and northern Spain (plus a sliver of Portugal); a partial eclipse is visible across much of Europe, northern Asia, North Africa and parts of North America. Totality lasts up to 2m 18s.
12 August
Perseid meteor shower
The most popular shower of the year, and 2026 is an excellent year: the peak on 12–13 August falls on a new Moon, so no moonlight to wash it out. Up to ~90 meteors an hour from a dark site, radiating from the constellation Perseus.
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.
