On September 1st, 2023, 9 hours after launch, I observed the Starlink-G6-13 stack from Yuzhno-Morskoy (near Nakhodka), above the Sea of Japan. I saw them for a minute low above the horizon as a faint grey cloud about one degree in length.

Canon EOS 60D, 18mm, ISO-3200, f/3.5, 15 sec. (the photo shows the blue color of the trail).
