                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
We had thin cirrus on and off all night, but still was a very productive
night for science. Good to mediocre seeing.
Adjusting the focus for the NA2 guider with the new version of TUI is much
improved.
On the very last object of the night the telescope halted because of a
rotator controller error (PR#745). Axis Init's kept failing. Strangely, a
few slew attempts cleared it(?) No time was actually lost.
Agile left mounted for daytime work.
