The hosts of the Waveform podcast broadcast live from Zaragoza, Spain, to witness a total solar eclipse. Setting up outside with specialized camera rigs, solar filters, and a custom eclipse timer, the hosts discuss the logistics of choosing Spain over Iceland or Greenland, share trivia about celestial mechanics and historical eclipses, and experience the sudden drop in temperature, changing light quality, and the rapid sweep of totality across the valley.
Hosts introduce themselves, explain the special live episode, and announce the total solar eclipse they’re witnessing in Spain.
The team details their custom-built eclipse timer, camera gear, and studio setup, emphasizing safety and visual quality.
The hosts explain what a total solar eclipse is, why it occurs, and describe the narrow path of totality that passes through Spain.
An in‑depth tutorial on using solar filters, ND lenses, and manual focus to capture safe, high‑quality images of the eclipse.
Hosts play a trivia game, sharing obscure eclipse facts and awarding imaginary cash prizes for correct answers.
They explore the terminology of eclipse chasers, discussing words like “umbra file” and the lifestyle of those who travel for eclipses.
They count down the final minutes, describe the visual changes, and share live observations of the shadow racing across the valley.
The hosts reflect on the experience, discuss future eclipses, and conclude the episode with final thoughts and thanks.
They describe the moment of totality, noting the corona, Bailey's beads, and the dramatic light shift.
Participants reflect on the awe, share personal insights, and hint at future eclipse events.
Choosing Spain for the Eclipsestory
The hosts explain why they traveled to Zaragoza, Spain, noting that the narrow path of totality is only 50 to 150 miles wide and Spain offered better weather odds than cloudy Iceland.
The Size Ratio Coincidenceinsight
The hosts explain the mathematical coincidence that makes total solar eclipses possible: the sun is 400 times further away than the moon, but also 400 times bigger, making them appear identical in the sky.
Helium Discovered on the Suninsight
A trivia fact reveals that helium was not discovered on Earth first, but rather identified via a color band observed around the sun's corona during an 1868 eclipse in India.
The hosts discuss how the eclipse poses a major test for Spain's power grid, with 5 megawatts of solar energy dropping off during the 90 seconds of totality.
The Origin of Umbrafileinsight
The guest introduces the word umbrafile, derived from the Latin word for shadow, as the official term for people who travel specifically to chase and observe solar eclipses.
Using a Colander for Shadowsstrategy
The hosts demonstrate how a strainer or perforated object acts as a pinhole camera during an eclipse, projecting multiple crescent-shaped sun shadows onto a surface.
The Purkinje Effect Explainedinsight
The host explains the Purkinje effect, which causes human eyes to become less sensitive to red light as ambient light drops, making faces and surroundings look monochromatic during an eclipse.
What is an Annular Eclipseinsight
The host defines an annular eclipse, where the moon is at its furthest point from Earth, making it too small to fully cover the sun and leaving a ring of fire visible.
“The width of that shadow is only 50 to 150 miles wide as it passes on planet earth.”
“The shadow is really elongated and will sweep in really fast, and it'll get darker faster.”
“The moon is moving away from the Earth very slowly at a rate of about one inch per year.”
“It's about half a billion years.”
“It wiped across the sky from right to left.”
“Seeing this on YouTube is way better.”
“The sun's coming back out.”
It's time for a bonus episode! this time, we flew all the way to Spain to record a live podcast under the total eclipse. We brought a ton of gear and crew to do our best to make it feel like you were right there with us so we hope you enjoy! This episode is in partnership with AirBnB!
