I was finally able to properly capture an image of a Starlink satellite ‘train’, a term used to describe how the satellites look in the days after a launch, after their release from a Falcon 9 rocket. Once initial health tests are performed on each satellite (in an initial parking orbit at ~340km altitude), they begin a months-long progression to their operational altitude, in this case of Group 6-9 to an altitude of 559km at an inclination of 43°. After release, they quickly start to spread out, and appear as points of light following each other, like a ‘train’.
EDIT: During the spring of 2024 I started to capture satellites in the sky that reflect a blue color, very unusual until recently. This capture confirmed for me that SpaceX’s new Starlink variant is likely responsible; the “v.2 Mini” satellites have new coatings on the underside designed by SpaceX to mitigate reflections, and apparently this di-electric mirror film may reflect blue light better than other colors. If you ever see a relatively bright satellite low over the horizon (from mid-latitudes) in post-dusk or pre-dawn hours, take a look through binoculars, you may be able to see the blue color clearly.
