Some ground team shots while we wait for video footage to return. In the first picture we've got Flight Director Diane Dailey and ground IV / CSA astronaut Jenni Gibbons, and in the second, EVA flight controller Megan Shutilka and many monitors.

Hooking up the cables while they're in eclipse - one eclipse earlier than expected!

(Edit - fixed name spelling.)

Woody's cable mating went nominally, Steve had one troublesome connector, but it seems like everything is hooked up as expected now. All actions that needed to be completed in eclipse to avoid shock hazard are now done.

(heh, Jenni keeps calling them N Zed G L connectors...)

Hinge bolts R7 and R8 have been driven - first with the PGT, then finger tightening them with "the AMS knob" - wonder if that's a repurposed tool from the AMS renovation EVAs? (and why the bolts need to be only finger tight?)

Bowen is driving the 8 bolts (M31 through M38) that secure the iROSA to the mounting bracket. Also, a good view of the electrical cable connections to the new array.

Swapping the PGT to let Hoburg get a couple of bolts that he's closer to. (Mostly I'm posting this one because you don't often get such a clear view of an astronaut's face during these spacewalk broadcasts.)

Edit - and last M-bolt is done - now to release the array and let it unroll!

iROSA is deploying!... straight into a handover.

Edit - there we go, video's back.

Deployment appears to be complete, but they need Hoburg to get eyes on the first 5 magnets on each side to make sure they've snapped together. (Just got that confirmation - deployment is succesful!)

Hoburg has released the R11 and R12 bolts to allow the tensioners to release and tighten the solar array blanket. Meanwhile, Bowen is over at the iROSA flight support equipment working to release bolts so they can rotate the beams that held the top iROSA out of the way, to access the lower iROSA on next week's spacewalk.

First FSE beam is free and will be tethered in place while the other support beam is removed.

Little hard to see due to the night pass, but they've rotated the nadir support beam to run parallel to the lower iROSAs.

Hoburg and Bowen are now working through some of the steps that would have been done at the start of EVA-88 to begin releasing the other iROSA. Hoburg has discussed removing anti-rotation devices (ARDs), but I'm not quite sure what those are. Meanwhile Bowen is going to release one of the boom end bolts (which will take quite a lot of turns - 245, more or less).

Edit - ooh, sunrise.

Wider-angle daytime shot of the two spacewalkers working on get-aheads, now that the sun is up.

audiio conversations between the Mission Director and various specialists at MCC-H are bleeding through onto the live feed
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

They cover the C2 & C1 bolts and, as named, prevent them from rotating accidentally.

Good view from Bowen's worksite of the boom end of the iROSAs with the deployment system rollers, with Crew Dragon Endeavour off to the left along with the Columbus module and Bartolomeo, and the SSRMS off to the right.

Also, Hoburg performed a get-ahead to retrieve a small piece of FOD off one of the magnets using the needle-nose pliers - he commented that the magnets are quite strong.

Hoburg is translating towards the airlock and cleaning up safety tethers.

(And now back starboard to make sure he double-tapped the CETA cart brake release.)

Both astronauts back at the airlock and preparing to ingress.

Bowen is also just about to ingress the airlock.
