Don Pettit(@astro_Pettit):Star trails from the ISS! Lots of cool physics to see in these. Stars moving as thin lines in the direction of our orbital path but forming arcs to the left of our velocity vector. Lightning flashes making purple spots into the time history. City lights streak by. A faint red glow is seen as part of our upper atmosphere. Surreal!
