Problem(s) Encountered:

The telescope hung partway with an error message about

where ha not initialized  (NOT exact phrase). It wouldn''t

move, even though we tried rebooting hill and mcgraw, and

multiple attempts at pointing it.

Solutions:

I finally got it out of its torpor by

home force ha=0  

or some such, which made the telescope think it was at the

meridian even though it was 4h west; I then walked it back to

the zenith, reset the pointing on the tilt meters, found a

bright star, and we were back in business.

It is possible that homing HA via the TCS GUI might also correct the issue.
