The sky is noticeably brighter than it was when the numbers were lower several days ago. WEATHER COMMENT: Wed Mar 6 18:41:16 GMT 2002 Cirrus has moved over. MKIV COMMENT: Wed Mar 6 18:41:32 GMT 2002 Paused due to clouds.

I pressed return to fix it. Soon after that a thick clouds covered the sun, I watched the telescope and it started to run away at a higher than clock-drive rate, it seemed to point ahead of the sun - where it will be later. So it was OK with the thinner cirrus clouds but the thicker clouds still make it runaway in pointing. There wasn't any stall or proghram crash, but that was probably because I stopped the observing program after the runaway started but before it tried to center on the sun to take more data. At the time of the stall I checked the filter position, the red filter was in place. Now that it's cloudy I've tried moving to various filter positions and the mechanism is working fine without any signs of binding or stalling. If the blue filter should have been in place when the "clr blue" message was up then maybe it would help to know if the red filter was in place before the blue, if so it didn't move at all. If red was to be in place after the blue then maybe that was correct and the "clr blue" was an "old" output message on the GUI screen. WEATHER COMMENT: Wed Mar 6 21:01:51 GMT 2002 Clouds are very thick so I've stopped all instruments.
