---=== OBSERVING PLAN ===---
	Science!
---=== OBSERVING SUMMARY ===---
Clear sky, windy and high dust level. We opened at 05:10Z when
the dust down less than 6000.
We observed two plates. One has been declared as DONE.
For other plate we have obtained sufficient S/N.
Accumulated dust is approximately 30000 so need the mirrors inspected for
possible cleaning.

Collimation is good for +9C.
Ventilation is not started because of high dust particle count (8500).
HDD cleaned up of old data that could be safely removed.

(because of using the cartridge 1 which wants -2200 in sp2 typically,
in the comrarison with other cartridges).
Now both should be in spec at +9C for all cartridges except 1. For the latter
one it should be within spec limits.
