4839	02:22-02:42	00:20	Segments 1:1 and 1:2 flopping back and forth during stacking, movement not well controlled. This lengthened the stacking time significantly. Noted that segment 59 moves more than others during tracker movements.
	09:01-09:02	00:01	First fan on Dry cooler making some pretty bad noise. Checked and it was not the shroud making the noise. Sounds like bearing noise.	Called: Herman Will take a look at it.
