Log

UT 01:13 - started LUCI GUIs - init all on LUCIs, test darks

luci1.20210501.0001-0002 - 2.51 sec dark

luci2.20210501.0001-0002 - 2.51 sec dark

-dark shows some light pattern on LUCI-1.. doing multiple (non-saved reads) to check - looking ok after 7 reads

UT 01:15 - putting N30 feldstop away in LUCI-1 to save time, then moving to N375 camera

UT 01:48 - LUCIs ready to go

UT 03:35 - LBTI checks proceeding - skies look clear

UT 03:36 - LBTI wrapping up, tests completed successfully.

UT 03:51 - taking quick L1 N375 image to check FS - ok

UT 03:52 - checking L2 - off slighlty will align L2 0003-0004 - now ok

UT 03:57 - reconfiguring for bino-LUCI - will do standard star first then science field

UT 03:59 - moving to pointing star

-DIMM has been <1.2" for LBTI

UT 04:04 - no stars in either guider

UT 04:17 - S860D - PhotStd Airmass 1.2

L1 0003-0006

L2 0005-0008

last L1 image FWHM ~0.97, last L2 image FWHM~0.91"

UT 04:26 - sending mixed mode to J1201

Rmag = 11.19

ESM preset failed due to ARGOS arbitrator not connected! LUCI-1 was authorized for ARGOS - why did that happen?

UT 04:32 - resending preset

SX side now out of focus ...

UT 04:34 - SX preset failed....if we were authorized for ARGOS then dichroic was in place which auto offsets L1 focus

DX guider shows FWHM~1" (while we wait for SX....)

UT 04:36 - resending preset again

- and no star on SX....

UT 04:38 - now doing another poniting check

UT 04:42 - now we have to collimate again

UT 04:46 - sending preset yet again (20min downtime)

DX guider shows FWHM 0.9"

-WFS camera lens railed ...

UT 04:55 - sending PA=180 version of script (original was PA=195)

WFSMag = 12.7

UT 04:59 - starting integrations

UT 05:00 - DX guider shows 0.9"

-star near AO Ref shows 0.57" FWHM L1, 0.6" FWHM L2, star near science target shows L1 FWHM 0.6" vs 0.67" L2

L1 0008 - 0.51" FWHM near AO Ref star

L1 0011- near AO Ref FWHM~0.43", 2' away near galaxy 0.54", compared to 0.61" and 0.72" DX Guider FWHM~0.99"

Airmass 1.17

L1 0015 - near AO Ref FWHM~0.44", near galaxy 0.55", L2 shows 0.66" and 0.64"

L1 0017 - satellite trail shot through where galaxy is

L1 0020 - near AO Ref star FWHM~0.39", near galaxy 0.50", L2 0.60" and 0.74"

L1 0025 - near AO Ref star FWHM~0.39", near galaxy 0.47", L2 0.59", 0.65"

DX Guider shows 0.8"

UT 05:48 DX Guider 0.84"

L1 0035 - near AO Ref star FWHM~0.40", near Galaxy 0.52", L2 0.61", 0.63"

L1 0007-0037

L2 0009-0039

UT 05:54 - completed as much as possile - D.Miller opening the loop.
