Summary

Quite a frustrating night, with both RSS and HRS giving us trouble, and high humidity closing the telescope around midnight. We completed 4 blocks and rejected 4 blocks. We did manage to do a high priority slotmode observation, and very nearly completed a high priority polarimetry block, which will still hopefully be useful.
RSS is now offline with a mechanical problem with the filters.
