| 4522 | 02:05-02:08 | 00:03 | Could not start pipeline on the PV camera. Tried bringing down PAS server, cycling power to the PV/CWFS cameras, and bringing PAS server back up twice with same result. CWFS Camera was working as normal. | Decided that we did not have time to get PV twilight images and moved on to instrument twilight flats. |

After clearing the skew and torque limit fault I could not get the tracker brakes to engage. | Called: Jim We tried a few things to get the brakes to engage with no luck. He told me to switch to Engineering user mode and to leave it for when he comes in. |
