Polarization, Diffuser/opal, and distortion. For the polarization and diffuser tests the Occulter was removed from the beam but the occulter mount/field stop were left in place. For the distortion test the occulter assembly was removed and the distortion grid was installed in its place. The Diffuser test used the Badder astro filter t=2.6e-4@1074.6nm ND filter. Weather degraded over the course of the test becoming too poor for observing within about 20 minutes of the end of the calibrations. Volcanic smog/so2 was tasted in the air within about 30 minutes of the start of the good polarization calibration, with obvious cloud textures passing over the site in the building camera. In spite of all this I think conditions were "ok" for the tests, at no point was there any obvious sky polarization by eye or halos around the sun. The polarization test got off to a bad start. Initally we removed the entire occulter assembly, but this appeared to be the wrong thing to do as the 2 beams were blending together with out a field stop. The test was stopped at 20:04ut. And a second test was started with no occulter but the field stop in place. This ran for 6 mintues before we lost guiding due to hitting the ladder at 20:17ut. The cal_clear step was restarted at 20:17 with the cal_clear.cbk and this should be considered the start of the polarization calibration test. This tested ended at 21:53 with the end of a second cal_clear cookbook. The diffuser/opal test started at 21:55UT and ran without incident (other then the degrading weather) The Distortion test started at 22:44UT with a little difficultly getting started; trying to figure out steps needed to safely re-focus the instrument on the distortion grid. I think I have a safe procedure now but we will want to think about this a little more for UCOMP. We are now down to 9 (7 once people have had time to look at the data) more observign days with COMP and some marginal weather in the forecast so if there are any issues with the data we should retake what we can at the earlest possible oppurtunity. ___end___ GENERAL COMMENT BY waters: Sat Mar 31 02:19:16 GMT 2018 Gave a tour to four people ealier today, right after the comp calis. They really enjoyed it!! ___end___ GENERAL COMMENT BY waters: Sat Mar 31 02:21:02 GMT 2018 The field lens inspection/air clean moved some spots but did not remove all of them. Will need a cleaning. ___end___ ONSITE STAFF: berkey, waters
