Nick stayed late to complete some altitude remaps and to give me a hand with the film crew. Thanks Nick! As a result of the inability to move the tertiary around the list of night engineering tasks that could be completed tonight became rather short. I felt comfortable giving Anjum the first few hours to work on alignment of a mask for Agile. After the telescope was returned to me I implemented the altitude remap data that Nick took. Humidity had dropped significantly and I was able to open at 23:30. After doing test slews I measured the Azimuth and Altitude velocity scales. Az Vel Scale was 578.0 measured 583.7, 589.4; 586.6 changed to 586.0 Alt Vel Scale was -635.0 measured -624.9,-626.8;-625.9 changed to -626.0 Next I took a pointing model at NA2. Around 01:00 the skies became photometric and after the pointing model was reduced and implemented I spent the rest of the night getting throughput data with DIS.

I saw no incidents of guider hangups tonight. The night went very smoothly with no problems. Seeing was good to moderate. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM ----------------------------------------------------------------------- 00:48 GUIDER 198( 371) -32 74 6.5 6.7 6.8 6.1 6.3 R+nd2 0.94 03:08 dis-slit 11( -86) 16 60 6.5 6.1 6.4 5.7 6.2 - 1.05 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 51 44 3 208 (SSW) 545 mstly cldy none 17:00 50 45 5 190 (S) 606 mstly cldy none 18:00 49 41 16 70 (ENE) 600 ptly cldy none 19:00 47 41 10 89 (E) 669 ptly cldy humid 20:00 45 41 10 91 (E) 688 ptly cldy humid 21:00 44 40 12 108 (ESE) 739 ptly cldy humid 22:00 45 34 19 113 (ESE) 725 ptly cldy none 23:00 45 33 14 118 (ESE) 586 mstly clr none 00:00 44 33 21 137 (SE) 597 ptly cldy none 01:00 44 32 19 138 (SE) 552 clear none 02:00 44 32 18 142 (SE) 595 clear none 03:00 44 33 15 143 (SE) 582 clear none 04:00 45 31 19 128 (SE) 615 clear none 05:00 44 30 20 127 (SE) 646 clear none 06:00 45 28 18 134 (SE) 709 clear none The convention used is north=0 degrees, east=90 degrees.
