Today, Bruce and Shane adjusted the attitude of the REAL trailer to restore it to the pitch and roll prior to TS Hilary. Background: rain from TS Hiliary caused the east and front of the trailer to sink slightly (about 0.2-degrees in roll and about 0.03-degrees in pitch). It was just enough that that beam was intersecting the ground to the NE of the linear array. Since August 21 until this afternoon we compensated by increasing the elevation angle on the BSU to 0.15 10 degrees. That is relative to the platform. So, if you see 0.1510-degrees in the data/images from 8/21 until about 2:20 PM PDT today (8/25), that is with a platform that is not perfectly level and it was our best effort at keeping the beam horizontal as it was before TS Hilary passed over.
