Sunphotometer diary 2008:

07.02.08 Sunphotometer measurements were started. JL, TP, Veijo Aaltonen (FMI)

19.02.08
 09:30 - 11:00 Sunphotometer was checked. JL

20.02.08
 14:00 Ice was melted from the rain detector. JL

29.02.08
 10:30 - 10:55 Sunphotometer was checked and ice was melted from the rain detector. JL

07.03.08
 12:45 - 13:15 Sunphotometer was checked and ice was melted from the rain detector, imperfect checking due to cloudy day. JL, HL.

15:00 - 15:15 The clock which was accidentally setted 1 minute behind time during the weekly checking was re setted to time. JL

17.03.08
 14:00 - 14:20 Sunphotometer was checked, imperfect checking due to cloudy day. JL

28.03.08
 14:00 - 15:00 Sunphotometer was checked, and tried to redirect due that "sunspot" alignment was about 3 mm of the mark. Wasn't able to get statisfying adjustment for the device and was forced to give up due to flu nad freezing wind at the heihgts. I'll give a new try on monday 31.3. DATA IS GOING TO SUSPICIOUS UNTIL THE SUCCESFUL ADJUSTMENT. JL

31.3.08
 15:00 Sunphotometer was readjusted, the inclination lockbolt was loose and the inclination angle was totally wrong. THE DATA BETWEEN 28.03 14:00 AND 31.3 15:00 IS VERY SUSPICIOUS. JL.

17.4.08
 12:00 Sunphotometer was checked and it was found that the heating cable might be to tight during the almucantar measurement. This might have been the reason for the robot errors. The cable was loosen all that was possible without right tools, but it has to be loosen moore. JL

22.4.08
 12:30 Sunphotometer was checked and the heating cable was loosened. There should now be enough loose in the cables for the device to do all the measurements without robot errors. In case of additional robot errors the heating cable should be totally removed from the zenith motor. JL, TP

14.5.08
 10:00 Sunphotometer was checked and the heating cable was removed from the zenith motor to avoid robot errors. JL

26.5.08
 13:00 Sunphotometer was checked. JL, MÄ

3.6.08
 14:15 Sunphotometer was checked. JL, MÄ

10.7.08
 13:00 Sunphotometer not checked this week due to cloudy weather. MÄ

15.7.08
 15:00 Sunphotometer was checked. Final alignment was about 1 mm off the target but further adjustment wasn't possible as the sky got cloudy. MÄ
