Two August Eclipses: Northern Total Solar Path Tomorrow and a Deep Partial Lunar Eclipse for Brazil on August 27–28

Overview

• The total solar eclipse, which occurs Wednesday, August 12, will sweep a narrow path across Greenland, Iceland, northern Russia, Spain and a small area of Portugal and will offer totality for up to about 2 minutes 18 seconds at some locations.
• NASA and the European Space Agency are launching high‑altitude balloon and airborne observation campaigns and backing live streams to record the brief solar totality and coordinate citizen‑science observations.
• Observers must use certified solar filters that meet ISO 12312‑2 or equivalent (for example welder's glass #14) during all partial phases because looking at the Sun without protection can cause severe eye injury; Brazil will not see the solar eclipse even partially.
• A deep partial lunar eclipse will occur overnight on August 27–28 and will be visible across the Americas, Europe and Africa with Brazil able to see roughly 95–96% of the Moon shadowed at maximum, about 01:00–01:12 Brasília time, and the event is safe to view with the naked eye.
• Local astronomy groups and observatories are promoting dark, elevated viewing sites, public watch events and livestreams to help people safely observe the lunar eclipse and to use the pair of August events for outreach and scientific data collection.
