                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
AzVeloScale: 582.4, 580.7; 581.5 (no change)
Clouds on and off first half but good seeing. Front moving in during second half
bringing precipitation. Radar returns in the county after 03:00.
Pointing with the Echelle and DIS was strangely off (between 1-2 arc min) when it
had been fine first half with Nicfps (as well as the previous day with DIS). Magna
sensor errors were not high, only difference seemed to be moving the tertiary.
