MC unlocked and misaligned. |
|
|
MC fell out of lock and was then quite badly misaligned. Mostly in pitch. I realigned it and it locked ok.
Turns out the MC falls often out of lock when the WFS servo comes on. I think the MC2_Trans history is not cleared on lockloss. I cleared it manually and realigned. Seems fine for now. |
