Summary

Cirrus passing. mostly clear

Start up of the system OK.

Right secondary and W# power on and set.

Instability of the system at BIN1 and Bin2, it was impossible to have a close loop.

We couldn't find the reason of the problem. Tomorrow is requested the Retro-reflector to test the reconstructor with retro and the possibility to rebuild some Reconstructors@Bin1
