ARGOS has priority for night, afterwhich AZ Science (service observing) - SO: S. Walsh (Tucson)

UT 12:55 - started LUCI software - ran init all

Taking 2 test darks - luci2.20190319.0001-0002

UT 01:37 - still closed. G. Rahmer on Skype with Wolfgang.

UT 02:17 - open and collimating on star near M67

UT 02:27 - collimation struggling

UT 02:39 - rolling on to M67 Collimation preset

UT 02:42 - collimated in the field - starting up lasers

UT 02:49 - sending science preset - lasers going

UT 02:52 - airplane closure

UT 02:55 - laser propagating again

UT 02:56 - luci2.20190319.0003 - psf degrading not round

UT 02:58 - spots stuck in holes

UT 03:01 - sharpening lasers

UT 03:05 - ready to propagate again

UT 03:08 - resending science preset for AO Ref star

luci2.20190319.0004-0005 - useless - satellite closure, plane inbound, and exposure started before lasers were set

UT 03:13 - taking exposure - loops closed

luci2.20190319.0006 - 2.51 sec x 26 NDIT

-psf not round

UT 03:16 - terminate lasers - satellite closure DIMM showing 1.4"

UT 03:20 - no corrections seem to be applied

UT 03:32 - still seeing no corrections applied - checking on FLAO side

UT 03:46 - reset truth sensing (possibly due to system thinking retro-reflector is on) - resending science preset

UT 03:49 - ripples/dumbbell/barbell on arbitrator

luci2.20190319.0007 - luci images show jumping, elongation

luci2.20190319.0008 - satellite closure - ignore - spots stuck in holes

UT 03:53 - elongated spots on patrol cameras, beam sharpening now

UT 04:05 - long satellite closure (~8min)

UT 04:24 - beam sharpening - (finished with 2nd long closure)

UT 04:47 - still working with Wolfgang on elongation in beam

- resending preset

- will cancel preset and re-collimate with ARGOS GS

UT 04:50 - guider / WFS show ~0.8"

UT 04:51 - sending science preset

UT 04:54 - taking exposures - look better

luci2.20190319.0009 - 2.51 sec x 26 NDIT

-FWHM 2.79,2.83 pixels - slightly triangular in shape - maintaining this across the 26 frames - fwhm 3.6 pixels at top

luci2.20190319.0010 - 2.51 sec x 26 NDIT

-FWHM 2.7pixels,2.79pixels - some elongation in images - natural seeing should be ~0.55" (given that DIMM Is 0.75")

-corner (bottom left) elongated

luci2.20190319.0011 - 2.51sec x 5 NDIT - elongated

luci2.20190319.0012 - 2.51 sec x 26 NDIT - elongated

UT 05:09 - taking another exposure

luci2.20190319.0013 -- 2.51 sec x 26 NDIT - same elongation

UT 05:10 - doing -20" +20" offset - seems to have induced ripples, NGS AO Ref star is a "comet"

luci2.20190319.0014 -- 2.51 sec x 26 NDIT - super elongated

luci2.20190319.0015 - some frames OKish, some super elongated with prominent tails

UT 05:39 - lasers turned off - end of propagation

UT 05:41 - putting blinds in, flexure off - closing LUCI GUIs out.

--Handing over to MODS-Bino for AZ Service Observing
