                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Local thunderstorms kept us closed all first half. Skies began clearing around
midnight overhead but radar still showed local activity for some time. Opened at
01:45 with mostly clear skies until just before twilight when another cloud bank
built up to the west.
No problems.
