Night Log

7:27 Handover from LBTI. Steve moving to zenith out of the wind so we can restart the adsec with the new software

7:44 The adsec arbitrator is not coming up. Brandon is on working his magic.

Brandon fixed the issues. the arbitrator came up ok, the new force open loop button is

8:00 Steve pointing and collimating after the new software has been deployed successfully. Seeing ~1.5". Conditions clear.

8:09 Slewing to OSCO target HD71514 R 7.52, elevation49, rotator 141 to start. We did not start collimating right away. It claimed it was moving the probe after the fact, probe position may have drifted, but it recovered after ~30 sec. Seeing 1.2" on the guider.

WFS mag 8.7
Fri Feb 18 08:10:40.402 2022 59628.34074539813 2 GCSL gcs.guidethread.alert left Probe position difference between requested/achieved is large 0.517379 (arcs). Probe position may have DRIFTED which may cause WFS to pause. 2022-02-18 08:13:21.275124| -13006 - [AOException] centerPupils: WARNING - RETRY: Camera lens temperature too low.

Steve is running the FLAOGUI to close the loop.

The rolled edge appeared as we turned on NCPA. High number of skip frames. Review Optical loop data to see why so many skip frames, likely high forces.

8:40 Slewing to star1 in RA14-15, bin1 PA60. Concerns about wind so abroting and slewing to next candidate

8:43 Slewing to Star 5 in in RA14-15, bin1 PA60. No guide star first time, so regenerated and resent. We have a glint from the moon that is causing hte wfs to be filled.

8:51 Executing Moon test instead. Star 9 in RA10-11 folder R=10.4. We will be 10.9 degrees from the moon. The guide star is too faint and we are out of range for the rerotator. Selecting a new guide star at PA270

8:58. New guide star of 12.25 clearly visible. This was needed since we fell out of collimation. Rotator now at 265 and decreasing, seeing 1.3-1.7"

R mag 10.4, OCAM seeing 11.2

Rolled edge seen when turning optical gain on (before NCPA on). Conditions are not very stable.

luci1.20220218.0103 was accidentally full frame but we do see the jump in the integrated RTD image

We opened loop,. Unstable conditions by actuator 374 may be a detatched magnet.  
Actuator 374 appears to have detached magnet:

9:14 Greg is removing actuator 374 from the list. adsec stop/start. Flat with 481 modes. That edge looks much better.

9:24 Resending preset to 2MASS J11010240240-0030040 for moon test, 10.9 degrees from moon. Seeing 1.2". R10.4, OCAM mag Rotator 237

massive tilt applied when centering pupils.

pupils also off when centering pupil so struggled to close loop. Greg had to manually adjust camera camera lens to align pupils. Suspect this occurred because background was so high OCAM mag 11.2.

Optimize gain drove way into safe skip and opened. The ranges are too big

MAJOR seeing bubble, highly variable

9:37 RIP from huge tilt during optimize gain.

9:44 Preset resent. Seeing variable. Can't keep loop closed

Executed subframed image with FeII 105 and BrGamma immediately after 106. Subframe did not reset.

9:56 Conditions are too unstable for AO. We are reauthorizing binocularly for full AO

9:58 Slewing to M67 ESM/67 forced bin2. Script magnitude R=12.6. Seeing 1.4-1.7. OCAM magnitude

Read error on LUCI2. Geirs was up not up. Conditions too unstable to keep loop closed

Greg verified the nifty new button on the flao gui works!

Moving on to poor weather backups

10:20 Slewing to APR second half telluric. Too low. LUCI2 mos error. Instrument Rotator moving to 210, el 90.
Grabber open, "rotator" at 340.977, prindle at 275.371, -4778

MOS storage to turnout, post condition violation translator to mask failed.

Check precon for init translator ok, init translator ok. Resolved and back in buisiness.

10:28 Slewing to Apr156 Telluric first half - HD95605. This target points us directly into the wind but winds ~2m/s on teh adsec, ~9/5m/s on the roof anemometer. Monitoring.

10:36 The guide star is way to bright and the guider is trying to guide on noise. Switched guide stars (PA90) and resending.

We are now getting 0.8-1.1" seeing on the guiders.

Science on HD95605


10:50 Slewing to science field Arp156. Seing a bit variable but is about 1". Acquisition images taken and seeing is 0.8-1.1" at 40 degrees elevation. We are switching to AO

10:58 Steve is reauthorizing monocular luci

11:01 Slewing to bin3 star 4 R=14.6 PA=0 - GD135. The moon distance 10.5 degrees. Safe skipping. Center star took two tries. OCAM magnitude 15.5. Bin3, freq 754,

Optimize gain repeatedly fails. Gain plots are completely flat. Moonlight too high

11:12 Slewing to bin3 R13.9 Star 10 in RA10, PA180 - G58-40. Initial setup is setup as bin2, not bin3. Bin2, freq 836. OCAM magnitude. No issues closing the loop or optimizing, applying optical gain

banding in image 0116. This was a short 1x2.51 acquisition image. Images after this were 26x2.51 cubes. Field stop appears to have shifted. Will realign before we start next science target.
LUCI banding.png

Images 117-118 NCPA was not on. No banding seen. Turned on NCPA

We do not see any obvious sign gains are ramping after large offsets.

TN#114753 taken during offset.

12:01 Huge seeing bubble. Loop opened, but we are on teh last image of the sequence. Image 0131

12:05. Sending preset to cats eye nebula this is pointed intot he wind. Winds ~2 m/s at the adsec. Pointing check needed

12:07 Resending preset to Cats Eye nebula. Seeing 1.25" at 45 in elevation.

OCAM magnitude is 13.2. R mag is 11.38

Seeing variable while closing the loop. Up to 2". Barry jinxed it.

12:20 Shell rip while trying to optimize. Steve is slewing us to zenith to recover. Greg is going to revert the software.

12:27. Seeing too variable. Steve has reauthorized us for binocular luci and we are slewing to Arp156 science.

12:31 At 37 elevation the seeing is varying from 1.1-1.7"

luci1 acquisition images 0012 & 0013 did not appear in readout 2 or in the rrtd, but 0014 (slit image) sdid. The images were retrieved from newdata. Running on obs5. I am running the standard rtd. Barry noted the same feature, also running on obs5 but with the luci_rtd_test verion for luci2

13:08 Seeing has been holding around 0.8"
luci1.20220218.0142-147, luci2.20220218.0016-21

13:20 Closing up
