GrimII is currently back on the observing floor, cold and powered up. 
It is available for use with the following limitation.

After a week of repair and troubleshooting by Dale Sandford it was 
determined that the lower right quadrant failure is a result of a 
problem inside the dewar. This quadrant was not able to be repaired 
at this time. Much more extensive and invasive work will have to be 
scheduled in the future.  The 3 remaining quadrants appear usable and 
nearly identical to before shutdown performance. There is still an 
ongoing problem that causes any quadrant to occasionally drop out. A 
proposed fix to this will be implemented in early January. Until then 
we believe this is an infrequent occurrence and the instrument will 
be useful.
For information about the state of the 3 active quadrants contact 
John Barentine at the site.
