Observing Summary:

After observing one object I slewed to another that was located in the north. The red OSMOS instrument package rotated against
the soft air tubes leading to the mirror near the fork and I started receiving warnings that the instrument electronics are not responding. I
manually slewed the telescope to free the instrument, then tried startup, etc in prospero but no luck. I decided to follow the IC reboot 
instructions and power cycling the OSMOS HE and IE boxes. I was able to do so successfully after much searching through the manuals. 
The procedure is documented but not clearly for a first time user. It is not obvious what things like the HE and IE are without extensive searching, 
as well as what the IC is and where it is located in the computer room (the monitor is easy to find but the box is not). Because of this 
confusion, I rebooted the machine that connects to the weather station instead of the IC at first since it is the closest  PC  to the IC monitor. 
It would be helpful to include in the manual that the IC PC is located in the right computer rack. This reboot and subsequent setup of the 
necessary applications on the workstation solved the problem that was caused by the movement. Unfortunately, by the time I solved this 
problem (2:00am), it had clouded over and I shut down shortly after. None of the masks need to be changed out, however the long slit in 
position 1 can be replaced with mask ID 584630.
