Overview
- The partial eclipse will unfold overnight on Thursday into Friday, with penumbral entry at about 22:24, partial start near 23:33, maximum around 01:13–01:15 (≈96% of the lunar diameter in the umbra), partial end about 02:51–02:52 and final exit near 04:01–04:02 (Brasília time).
- Because the Moon will pass deeply but not fully into Earth’s umbra, observers may see reddish or orange tones on the shadowed portion without the full red "blood moon" effect associated with a total eclipse.
- The event will be visible across Brazil and parts of the Americas, Europe and Africa, with the best local viewing window in Brazil roughly between midnight and 02:00 if skies are clear and light pollution is low.
- Public programs are planned: Maceió’s OAGLL and CEAAL open to visitors from 19:00 until about 03:00 without preregistration, and Campinas’ Observatório Jean Nicolini runs a 23:00–03:00 session limited to 200 people with prior registration and a small cash fee.
- No special eye protection is needed to watch a lunar eclipse; binoculars or telescopes will reveal more surface detail and atmospheric dust and pollution will affect how strongly any red tones appear.
