Clouds very thick and low now. PSPT COMMENT: Wed Aug 6 20:14:57 GMT 2003 Old and new CaK filters have different tilt. Secondary images appear using new filter so washer stacks were measured and then swapped, maintaining their also different orientation. Old stack was 0.1365 inches. New stack was 0.0760 inches. In the swap process, the ND filter in front of the new filter cracked while tightening down the hold-down screws. I had to swap the ND filters also. Randy may need to adjust the exposure if the ND values are different. New filter with old tilt and ND is installed in PSPT. No sun at this time to test the new configuration. WEATHER COMMENT: Wed Aug 6 21:20:24 GMT 2003 Raining lightly. WEATHER COMMENT: Thu Aug 7 01:07:38 GMT 2003 Stil in heavy overcast and light rain. No useable data today. Shutting down.
