On Monday, March 9 at about 11:24 p.m., the International Space Station made a full-moon lunar transit that was visible (with magnification) across a 4.8 mile path that passed through Santa Barbara. In the center of this path, the duration of the transit was only 0.71 seconds.  I captured the event from Los Patos Way, near Stella Mare's restaurant.  

This image is a composite of frame grabs (every other frame) from a 4K video shot at 30 frames per second, at a shutter speed of 1/1000 sec.  I shot the video with a Canon 5D Mk IV and 600mm lens.

Mother Nature was kind enough to provide a brief and very unexpected clearing of the sky in what was otherwise a cloudy night.

A crew of three is currently aboard the Space Station.  It orbits the earth every 92 minutes, or just over 15 orbits per day.  It travels at a speed of 17,100 miles per hour, at an altitude of 254 miles.

Way cool, Fritz Olenberger! Technically superb videography and editing into a composite. It almost looks as if the Space Station is orbiting the Moon. Thank you! A question: Is it possible for you to post the video on YouTube? Does it look as good as a video?

Thank you! I had difficulty posting the video on YouTube, but you can see it on my Facebook page (March 10, 9:54 a.m.) It is best viewed on a large screen. The video is only 3 seconds, and the transit is only about 0.7 seconds. At 30 frames per second, converting it to slow motion would make it look choppy (and I don't have the software to do the conversion).

For other photographers who may want to try to catch a transit by the ISS of the Moon (or the Sun , but be sure you have a safe filter!): https://transit-finder.com
