                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Velocity Scales: Was 590.0, Measured 586, 590.5 Avg 588.2 no change made.
 Rather poor seeing second half due to strong winds from the east.
 At 04:40 wind speeds became to high to stay open. We closed and did not
 reopen.
 When I was closing for the weather I noticed that the ion pumps for Nicfps
 and DIS Blue Camera were both pegged. Both cameras had started a warming
 cycle. I was able to return temps for each instrument so they were back
 in the normal ranges however both still remained high.
