Today,  I have done scans on the mismatching as requested by M.Cifaldi and C.Taranto. The ITF was misaligned, so together with M. Mantovani we manually realigned to perform these scans. Then the commissioning team performed measurements on the centering of the CHRoCC.

The shift was dedicated to maintenance. Here is a list of the activities reported to the Control Room:

• standard Vacuum Refill from 6:00UTC to 9:30UTC (VAC Team);
• cleaning of CEB, clean room (Ciardelli, Menzione with external firm: from 6:00UTC to 10:00UTC);
• maintenance of the boiler at TEB (D. Soldani)
• excavation operation at NEB
• installation of accelerometers at WEB AHU, shaker installation in the NEB hall(I. Fiori, M. Tringali, F. Paoletti, R. Passaquieti)

all the maintenance activities listed before were completed at 12:00UTC.

13:50 UTC As requested by F. Sorrentino, I started again the scan.
