April 8, 2024 Total Solar Eclipse: Here's what you need to know -Smarter Every Day 295

Summary by Krater

Smarter Every Day visits solar eclipse expert Dr. Gordon Telepun to explain nine science stations and phenomena to look for during a total solar eclipse, including temperature inversion, pinhole projection, glasses safety, sharp and fuzzy shadows, wind effects, convective clouds, animal behavior, the Purkinje effect, and shadow bands.

Answers: What science phenomena can you observe during a total solar eclipse?

• total solar eclipse science
• partial phase phenomena
• temperature logging during eclipse
• pinhole projection
• eclipse glasses safety
• Purkinje effect color perception
• shadow bands

What it concludes

• Temperature decreases at ground level during partial eclipse phases before the upper air temperature sensors drop.
• Welding glasses are not certified for solar eclipse viewing because they fail to block the right amount of infrared and ultraviolet light.
• Shadows from objects oriented perpendicular to the crescent sun become fuzzy while parallel shadows remain sharp.
• Eclipse breezes occur when cooled air from distant umbra-shaded valleys rolls down toward the observation site.
• Convective cumulus clouds can dissipate before totality as the eclipse shuts off ground heating and moisture.
• Animals such as crickets and bees alter their daytime behavior and mistake the eclipse darkening for nightfall, causing temporary increased activity before totality settles them down.
