---=== OBSERVING PLAN ===---
Science!
---=== OBSERVING SUMMARY ===---
Mostly clear all the time. The levels of dust was between 2000-3000 also
all the time. The humidity was between than 25-50%.
We observed SN 82,N full stripe and obtained significant S/N for the
plate 2695 (Cart.4), but not finished it.
At the time of imager's observation the 'skyL' for ccd45 was >300 some time.
The details in to 'log' and 'problems' section.
---=== OBSERVING LOG ===---
Afternoon:
----------
All systems checked and working properly.
Ran 'byebye' on 54396.  As of 21:50Z this leaves 43G available on /data
partition and 659G available on /files partition.
Spectro focus set for ~4C.
23:23Z - Began ventilation.  Doors and louvers opened, fans on.
Night:
------
00:20Z - mounted Imager in to enclosure
00:31Z - run 7120 bias on telescope.
01:00Z - opened enclosure
01:08Z - telescop ready
            SN stripe 82,N tonight
01:17Z - start run 7121, at lam=111
01:23Z - start ramp, lam=113, fr.19
01:31Z - start science, lam=115, fr.31
         focus is happy at fr.22
         skippy is happy at fr.26
         the skyL for ccd45 was high: >300 from the beginnig observations
         and up to ~fr.195.
         We check telescope: have not additional sources of light.
         seeing ~ 1.3", excluding fr. -8473  -8638  -8854;  T=10.5C
sp2>  -969  -1574  -1671;  T= 8.3C
        Average T=9.4C
        Expected night temperature at the end of the night is ~4C
        Spectro collimation set for 4C
                Difference of 5.4 degrees (colder) = -5400 steps
