It was more like glowing dust trailing a good distance. Turquoise wish a slight light green hue to the train. Definitely had small debris break offs and ended with a little pop emitting a slightly light yellow glow that dissipated instantly as the blue mass died out rapidly after.
Small fragmentation dust clouding. Broke into maybe 3-4 faintly visible masses after the light yellow pop at the end. Kind of like it fizzled out
Small dust trail glow and 3-4 different sized fragments as it popped and fizzled out rapidly.
