We have used all the available balancing mass and need more.  We will bring more from the staging building and continue balancing in the morning.  Meanwhile, the ISI is unlocked and very unbalanced.  We will continue in the morning in an effort to at least get it reasonably lockable before we relinquish if not completely balanced before leaving it.

When we got started there was Baffle hardware to install and lots of cleanup.  As well, we marked the PR2 iris with an upside down dog-clamp and removed both irises.
