When you’re Thierry Legault and you want to challenge yourself, the bar is set pretty high.
“This is a challenge I imagined some time ago,” Legault told Universe Today via email, “but I needed all the right conditions.” The challenge? Capture a transit of the International Space Station of not just the Sun — which he’s done dozens of times — but in front of a solar prominence.
Legault said the transit of the prominence, which he captured on August 21, 2015, lasted 0.8 seconds. His camera was running at 40 frames per second, and he got about 32 shots in that time.
