Also Present:

Problems: 

We had problems with the Hexapod at 11:40 pm. We were taking standard stars SDSSJ0200-0000 in i,g and u, and after finishing the g-band image of 15 s (257852) the system gave us the Warning "Interlock SISPI (HEXAPOD) is now broken" and "Inerlock DECAM (SISPI) is now broken". The status of HEXAPOD was error, but the X,Y and Z values were still below the limits.

Tim Abbott verified the values of Hexapod with the laptop and realized that values were off the limits. Since we had the same error than last night, Tim decided not taking any risk and I agreed to leave the system as it is. We have lost two nights due to technical problems, and I fear more nights will be lost due to malfunctioning hexapod.

Comments: 

The night started well, few clouds and seeing around 1.5''. The seeing keep fluctuating around 1.3''.
