                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Cloudy skies with numerous nearby thundershowers and radar returns.
 The skies cleared shortly after 23:00 however there were still
 threats in the area so we delayed opening. The approaching storms
 never did reach us and I opened at 02:00.
 No problems the remainder of the night.
