The vacuum nozzle that we originally modified for a lower noise level has lost the Viton strips that were installed. I reinstalled thicker rubber strips and reinforced these with an aluminum backing strip. This was only tried for a few hours this afternoon so time will tell.

 We were able to clean 79 meters today ending at HSW-2-054. We began relocating the generator and lights.

Total meters of Y-Arm tube cleaned = 907.
