During the fly-over the ISS was traveling toward the southeast and crossed the ‘Square of Pegasus’ asterism, and then past the ‘Circlet’ asterism in Pisces coming within a few degrees from the planet Uranus. The images are each 3.2 second time exposures – long enough to capture the dim stars making up the ‘Circlet’ – but also so long in the sense that in 3.2 seconds the ISS has moved enough to show up as a streak of light, like star trails in longer time exposures. This animated graphic is slightly faster than the actual event but I have set it to give a sense of how quickly the ISS moves and how its brightness increase, peaks, then fades.
Looking toward the east were the stars of the Pleiades and, lower toward the horizon were Jupiter and the Hyades. Obviously I couldn’t resist!
And then this morning there was a neat contrast between the reds and pinks toward the west, the setting waning gibbous Moon, and some high thin cirrus clouds.
