Overview
- The total solar eclipse on Wednesday, Aug. 12, will cross a narrow path in high northern latitudes and parts of Europe with maximum local totality of about 2 minutes and 18 seconds.
- The solar event will not be visible from Brazil, but the Observatório Nacional will livestream coverage beginning around 12:00 Brasília time so Brazilians can follow the phenomenon online.
- A deep partial lunar eclipse on the night of Aug. 27–28 will be visible from all Brazilian states with roughly 95–96% of the Moon expected to be covered and no eye protection required for safe viewing.
- NASA and the European Space Agency have planned high-altitude balloon and aircraft campaigns to study the Aug. 12 eclipse and its atmospheric response, and the event coincides with the Perseids meteor shower while aurora during totality remains extremely unlikely without a strong geomagnetic storm.
- Observers should use certified solar filters (ISO 12312-2) or welding glass number 14 for any direct solar viewing, follow local astronomy groups for recommended viewing sites and expect the two events to offer both public outreach and targeted scientific study of short-term atmospheric changes.
