The International Space Station ISS was brightly visible flying across the sky monday evening at 10 PM in SW Switzerland. But if you were at the right place you could see ISS transit across the Moon !
This was visible from within a long path going from France over SW Switzerland near Geneva and then over Chamonix Mont-Blanc and into Italy.
I drove 1 hour from Vétroz , Valais canton in Switzerland , over 2 mountain passes to reach Chamonix where I filmed the Moon and ISS flying across . Shown here first in realtime , then in slow motion and further close-up.
The ISS takes almost 10 minutes to fly from one horizon to the opposite horizon but the actual lunar transit lasts less than a second.
I used www.transit-finder.com and www.heavens-above.com to find the precise timing and location to see this.
In this case the ISS was brightly sunlit , at magnitude -3.1
Sometimes ISS flies within Earth's shadow and is not visible then except for a very short moment when she flies in front of the Moon, backlit.
Camera Canon EOS R8, Lens RF 800/11 plus 1.4 teleconverter and digital crop zoom on tripod. Originally filmed in 4K60 then edited with crop zoom to 1080p FHD.
Final image shot handheld with another camera, EOS R6 , RF 600/11.
