Right now to revise this (in an effort to keep everything accurate if I

Saturday 24 June.
Launch time 20:43:06 UTC.
Launch window is 10 mins 6 secs.
Pane 1 runs from 20:43:06 UTC to 20:50:05 UTC.
Pane 2 runs from 20:46:12 UTC till 20:53:12 UTC.

A launch in pane 1 results in docking on Monday, a launch in pane 2
results in docking on Tuesday. Thus at this time it looks like the
preference is to launch in pane 1 (again running into it depending upon
the ascent performance margin available), but retarget for pane 2 at
20:50:05 UTC if they aren't off the ground by then.

The ascent pass should be best visible over central Europe. Twilight is
going to interfere with observations from NW Europe.
