                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Vel Scale
 Was 574 measured 580.5 changed to 580.5
 Alt Vel Scale
 Was -606 measured -606.2 n/c
 Clouds, dust, high humidity and wind kept us closed most of the night.
 We were able to open by 04:15. Seeing was quite poor exceeding two
 arcseconds.
 At the beginning of the night the weather server and the DHCP server
 crashed. It took several hours for Jon Brinkman to get them back up
 or to get an alternate server up (in the case of DHCP). This is why
 serveral hours of weather info is missing from the log below.
 No other problems.
