IHA3E01 was flagged for a stuck position. Had OPS abort scan and zero the harp back to the home position (out limit). Attempted to cycle the harp, but scan function did not respond. Performed a hard reboot of the harp control chassis (ioceas2hrp), verified the ioc restored. Cycled the harp again with no issues. The harps for iocea2hrp are fully operational.

Pass 2 separation looks good.

We did a quick separation check at AE. Found that an AS10H adjustment brought things within spec. We would still like to do a full 5th pass separation check at some point but for now we are rough steering as far as we can go.

Made it to 5C dumplette but beam quality is clearly poor.

Now we are doing FOpts and corner harp swipes to figure out where we need to start healing optics.
