Problem(s) Encountered:

When I slew the telescope to the target, it said Slew: unknown status! and I could not find the pointing of the telescope in the Sky Display. So I used the control panel to point to my target this night.

Solution:

JSkyCalc failure was due to loss of connection to the TCS, stemming from the network weirdness on Saturday.  Restarting JSkyCalc has resolved that issue.
