Given that Wheelock is in "free time", MCC-H would like him to reposition a handle in the CETA cart, because it seems to have been knocked out of its nominal position. He should be able to do it before the APFR egress assistance tasks with Scott.

I think as long as the mast is fully extended 100% as it is now, the SARJ can move again, I believe the structural concerns was more to do with having a partially deployed mast instead of the arrays.
I'm just remembering back to 4A when one of the tension wires came off the reels...the array went out most/all of the way, but it wasn't fully tensioned.  After they retracted slightly and replaced the wire, the array was fully redeployed and then latched...that's why I'm wondering if there's anything left to be done there...

Looks like lightning flashes down below on Earth were visible in Scott's helmet cam view.

I was surprised to read in the Electric Systems Manual that the mast may have only 10% of its structural strength depending on how far it's deployed. Everyone's tension is now in the mast, where it should be. Time for much toasting.

Just a note to say how nice a person "Wheels" is.  He loves to tell the NASA story with kids and he is a great person to know.  This is a picture from his recent launch party with some children from England and my daughter.

Just like with Skylab, these guys (and gals) are showing that they still have the right stuff (not that I ever doubted it).

While they continue to wrap this EVA up, I have to say that was an awesome job they all did today - especially Scott.   It was very impressive to watch all the planning really come together they way they hoped.

My only question now is does anyone have an idea when they expect to know about the state of the OBSS instruments after all of this?

Well, you need to have the OBSS grappled by the SRMS to power it, so we will know when that happens.  As for when that will happen, according to the TV schedule, it will occur at about 1:58pm eastern... so an hour and a half from now.
