Brad Holden and Bob Nichol were observing. They worked on spectroscopy of distant galaxies. There seems to be something strange going on with Remark that they encountered. The numerical coord.'s change in remark during a slew, but the telescope position "dot" does not move. I closed and opened the remark window a few times and it seemed to fix this for the moment. Also, they seemed to be having very slight tracking problems...they described as a "wiggly" appearance. (Although I did not seem to have this problem.) I reinitialized the axis and this also seemed to clear up the "wiggle".
