              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Observers: Greg Zengilowski, Trevor Dorn-Wallerstein, Angelica Rivera.
Carolyn Morris.
When facing the telescope, the lower right mirror cover petal seemed to
stick during afternoon checkout. I used TUI to open and close the covers
for test slews, but when I closed them again, this petal remained open. I
opened and closed them manually several times, and this petal closed and
open with this rest. I had no problem with it after that.
After mounting Tspec for JH06, I asked Jenny to slew to her target. We got
another "motion error too large" in azimuth. We were pointed at ~ -27
degrees, attempting to slew to ~ +20 degrees. I stopped and restarted the
axes twice, and she got an error during slew, and we saw a current spike
of ~10 A. I stopped the axis motors, and then slewed to -40 in Az. This
worked, with good current feedback. I asked her to slew to her target
again, and it was successful, with oscialliating current feedback no
higher than 5 A. It took less than five minutes to recover, so I did not
count this as time lost.
No problems the remainder of the night.
