The International Space Station (ISS) orbited across the United States last evening and on this particular orbit reached an altitude that was 2/3’s of the way to the zenith, 90o, as it passed over my part of the world. This is a ‘Ground Track’ graphic from the Heavens Above web site that shows the viewing area for my location where the ISS would be at least 10o above the horizon.
Using the Heavens Above web site a star map showing the path of the ISS may also be generated.
So despite clouds moving in the ISS was very visible shining through the clouds as it rose in the southwest and then reached its greatest brilliance as it headed toward the northeast passing near the stars of the square of Pegasus. Each of these ISS Trails is a 4-second exposure at f4.5; ISO 1600; 18 mm.
