telescope ready for LN test.

05:10PM

LN some test to work with the skip frame scenario.

Internal rotator moved and loaded reconstructors wit Gain 0, there is not problem.

Carmelo closed the TT loop, tilt observed in the command, skip frame on

Decided to go ON SKY and to force to be close dome.


Note: For close dome TTofloading done with the enable RR mode. But time to open is very close.

05:31PM

Open

05:39 PM

REady to go from OSA.

some clouds passing.

First target: EL 47

No loop close yet.

06:04PM

06:19PM

low order modes to close for acquisiton of stars (better pupils).

Loop open skip frames.

clear adsec

close loop again with only TT.Increase more than 2 and it skip frames.

skip frames.

stopAO

06:24 close loop

06:29PM

DEbug. CAmelo asked florian if there are something in sign flip about the gains.

loop closed with negative gain:

loop closed.

It is not that......

Interface of gain LN

The Rec is the same one used last time on sky two days ago.

06:32PM

Recenter stars ->Guiding.

Reset BCU

Try to close the loop. skipping

JC asked about if the patch was working and Florian confirm it. Not rec applied during the skip frames event.

06:40PM

off sky and takng darks for the WFS.

06:43pm

Elevation 54.

still clear sky

06:45PM

recenter stars

close loop

not doing anythng.

06:48PM

06:49PM

seeing 1.5 arcsec

Revert REC services for KL18

try close loop

open loop

06:53PM

close loop

apply large TT gain

open loop

It seems the loop diverge.

several tries with the same outcome.

06:58PM

recenter.

07:03PM

close three stars.

same behaviour.

loop open.

try again after looking at the pupils.

same behaviour.

07:07PM

doing some active optics to improve PSF.

recenter CCD.

close loop try.

same behaviour.

07:12PM

recenter

close loop.

only TT

drifting

not correcting.

try again.

it seems working

07:17PM
  • bright star in.

Changed to KL_20

close loop 30 modes. Ground layer working.

TT gain ->-3

PSF 0.2"

08:12PM
  • thinking to move with Highlayer
  • Carmelo keeping workiing with the ground layer stabilizaiton
08:19PM
  • getting worst psf.
  • increasing wnd speed.
  • Tom screen
psf_tom_0819.png

ready for high layer.

08:21PM
  • seeing 1.4"
  • seeing evolution plot.
  • variable seeing
seeing_plot_0829pm.png

  • close high layer.
  • close TT, 7 modfes
  • Xianju asked if the request of status. Florian verify that it is ok
08:33PM
  • skip frames and stopAO
  • recover. close loop agian
  • ground layer 60 and Hgh layer 7
8:52

  • close loop both.
  • seeing 1.5", variable
  • looks a good psf.
  • Tom comments; good results for both loops.
  • Tom image;

loop closed. Starting upper layer acq.

09:02PM High loop closed.

09:04

seeing 1.4"
  • IR PSF is giinv 0.7" almost not corrections.
  • still waiting to close high layer
  • stop AO
  • move away for ground layer dark.

09:09PM
  • Xianju set the 641modes flat as default flat for LN

09:28PM

close loop ground layer.

Closing the high layer

close for wind speed. Loop unstable
