The config3 transition yesterday went:

1. Move the east horiz array up 3 slots.   (This measured at \~4.87m for the top of 5b's boom to the base plate.) \[started \~0600\]

2. Move the west horiz array up 3 slots.

3. Move 6t and 6b up.

4. Move 12b up.

5. Move 5.5m and 4.3m up to \~5.8m and \~4.8m (also T/RHs) \[done by 0830\]

6. Tear-down upwind and move to staggered upwind, sequence 11u \-> 3u \[done by 1230\]

7. Remove upwind bases \[1530-1630\] 

When we started to build config 3, we measured 3.254m from the config 3 reference line  to the top of 5b's boom (of course, after raising it to its position).  New measurements for other sensors:

6t: 3.252m

6b: 3.250m

12b: 3.275m

(I didn't record new measurements of the 2 profile sensors.)

All of the upwind sensors were set to 3.261 = 3.254+0.7 to the top of the clamp +/-1mm.
