Was this a jellyfish launch?

Low

Sun 1° below the horizon at liftoff — the sky is still too bright for the plume to stand out.

Twilight times at the pad (Mahia, NZ) for the morning of the launch.

What's a rocket jellyfish? When a rocket launches in twilight, the ground is dark but its exhaust plume climbs into sunlight high above. The expanding plume glows against the dark sky in a jellyfish-like shape.

Example: Owl New World (RNZ)
