I rebooted the softIOC for the cRIO since that was showing up as disconnected.</div>

The original external #1 HTSB board was reading bad humidity values so I replaced it with another one, that one is coiled up under the mounting fixture in order to read the ambient temp/humidity.</div>

Since external #2 had a label that said shell I slid it under the plastic bag into the L1C area on beam left side.</div>

Both of those sensors were reading extremely high ~70 % RH and when I went to adjust the positioning on them they went over 100% and when I removed them they actually came out with some water on them. They both are now hanging from the barrel outside of the
bag to try and dry them out.</div>

Gently pressing along the bottom of the bag it feels like there is a substantial amount of water being held by the bag.</div>
