6454	23:00-23:00	00:00	During Ops, found some air bearings are not releasing air after structure sets down. Notably pad 7 & 8 on Foot 1 and pad 7 & 8 on VSS.
6453	22:30-22:30	00:00	During Ops the external dewpoint sensor was found to be malfunctioning. Reading a dew point of approx -3C when it should be reading approx 8C.	HK is going to try cleaning it.
6455	21:50-21:50	00:00	During Ops, large puddles found in dome after today's storms. It has been determined that this was due to dome panels and shutter seals needing to be replaced.
