Overview
- The deep partial lunar eclipse will take place overnight Thursday to Friday, Aug. 27–28, and will reach its peak near 1:13 a.m. local time when about 93% of the Moon’s diameter is inside Earth’s umbra.
- The event is visible across Argentina and in parts of the Americas; lunar eclipses are safe to view with the naked eye and do not require special eye protection.
- Detailed phase times for Argentina are: penumbral ingress ~22:24, partial ingress ~23:33–23:34, maximum ~1:13, partial end ~2:52, and penumbral end ~4:01–4:02 (local times).
- Meteorologists forecast the Santa Rosa storm could bring heavy clouds and rain over the AMBA (Buenos Aires metro area) during the eclipse window, so Planetario programs and media recommend monitoring conditions and favoring open, low‑light sites or organized viewings that depend on clear skies.
- The Moon’s reddened hue comes from sunlight refracted and filtered through Earth’s atmosphere before it reaches the lunar surface, and the event follows strong public interest in the Aug. 12 solar eclipse while several notable solar eclipses are scheduled between 2027 and 2030.
