Problem(s) Encountered:

Despite restarting prospero several times and changing filename, only every other exposure was recorded in the file folder (?!). Did a work around and saved all the data taken.

Solution:

Closed out Prospero and quit out of the Caliban terminal window.  I then quit the program on the IC PC (via the Raritan) and shut down the IC PC.  Next, I shut down the Caliban disk enclosure.  After 30 seconds, I powered up Caliban, then the IC and restarted the data-taking processes.
