                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
AzVeloScale: 575.5, 573.4; 574.5 (changed to 575)
During afternoon checkout NICFPS files were all zeros. A simple nicfps expose init
fixed it.
Apollo was able to use their time tonight after all. They struggled with a few
issues but still managed to get a successful return.
Around 03:00 the winds shifted direction and speed. Outside temperatures dropped,
dust rose and humidity increased. The dust contained a substantial amount of pollen
(as seen on hard surfaces outside). Closed at 03:40 as conditions worsened. When
closing I (and the 2.5m observers) noted a distinct strange smell in the air
outside; not exactly smokey but maybe smoke + pollen. Could not open again.
