Details:
Both the town of St. George (Utah) and the ISS high overhead exited Earth's shadow at the same time just after 5AM MDT on Apr 29, 2020. The ISS ran through twilight in < 30 seconds, however, while it took St. George 1.6 hours to proceed through astronomical, nautical, and civil twilights before the Sun finally made its appearance at Earth level.
Photo data: Panasonic G9, Lumix 20mm lens, IOptron SkyTracker Pro. (f/2, ISO 400, 60 second) exposure--the ISS appeared 20 seconds into the exposure. Also, the star field was photographed earlier in a series of 30-second subexposures when it was higher overhead and darker, and stacked with the ISS subexposure to reduce noise and light pollution in the final image.
