---=== OBSERVING SUMMARY ===---
We finished plate 2739 and acquired signal on another.
We had to close ~08:40Z because of pollen.  It's too bad because the sky
transparency was great and the seeing was  3976 4162 4267 T= 16.1C
sp2> 6721 6077 6257 T= 14.1C
        Expected night T= 16C
        Spectro collimation set for 16C
                Difference of 0 degrees = 0 steps (sp1)
                Difference of 2000 degrees (warmer) = +2000 steps (sp2)
