Details

All times are UT
Files are luci1/2.20171211.NNNN.fits

00:18 Sunset, overcast, T = +1deg, hum = 20%, wind = 10-15 m/s

04:30 Sky is somewhat better, we give it a try, David opens up, checks pointing and collimates

Seeing-limited AFC-spec

05:25 Preset to an A-star at 3h+42deg, preset OK, align OK; AFC-start OK
N3.75, LS_2.0_1.5, J, 1.25mue, 30sec intervals, no nods
SRR: #7-12, MER: #13-18, 300sec
High elevation, start at 79deg, AFC-data look super !!!

Still pretty cloudy outside, guider gives about 1.3"

06:40 Preset to an A0-star at 80deg elevation, same setup as before, this time with dither
all OK, SRR: #24-29, MER: #30-35, clouds become very thick at the end,
lost guiding but didn't affect our goals

Seeing on guider 0.8-1.7"

07:55 Preset to an A0-star at 80deg elevation, z-band tilted at 0.95mue, 30min SRR, 30min without any flexure correction

08:05 Coudn't start, closing up, clouds too thick

Doing closed-dome tests instead, same setup as above, J/1.25mue, Ar,
track preset, 30min SRR AFC, 30min MER w/o flexure correction,
SRR: # 44-49, MER: #50-55
