Summary


Very cloudy start night.

Telescope rebalance. Lost twilight flats, took too long to refill Pisces. With those two issues the telescope was not hand over at 4pm

We had problems to do active optics and to finish the presets, This is due to the bad sky conditions that made very hard to acquire and close the loop.

The thick clouds forced to stop the observations and we decided to finished (12:40)

Details

1:41 preset,OBJECT=Foc,MODE=ace,GS=1,RS=0,PA=-103

preset failed, too cloudy, not much flux to acuire the star.

~2:00 preset,OBJECT=Foc,MODE=ace,GS=1,RS=0,PA=-103

doing manual active optics with John on the phone.

2:12. resend preset same star. hard to converge the active optics.

2:20 preset HR8799.

There was a vignetting from the rotator, it wasn't off enought.

close the loop manually, ok, but there is an issue about the maginuted of the star.

3:52 preset,OBJECT=FS6,MODE=ace,GS=3,RS=0,PA=-66

Failed, we can't acquire guide star in the GCS.

04:24 preset,OBJECT=HD19626_2,MODE=ace,GS=38,RS=0,PA=0. Not star in the guide probe Resend the preset to acquire on-axis.

It is geting hard to do the collimation, we have good flux on the WFS.

5:30 preset,OBJECT=IS_ERI,MODE=active,GS=0,RS=0,PA=0

failure during the close loop and the secondary rip.,.. Primary mirror, Panic

After the primary is recover the next presets give error in the preset. r esult from IIF 1call him setting reval val to 1 ===> Active Optics loop is not running

Failure to close the loop we can see that the comands are not going to the seconday *6:35 preset,OBJECT=IS_ERI,MODE=preset, IS_ERI, MODE=ACTIVE, GS=0, PA=-21.0000 ADI active,GS=0,RS=0,PA=0 send this info to Marco

Close the loop. Open the loop after applying some offsets from the AOS. the loop open. 07:20 preset, IS_ERI, MODE=ACTIVE, GS=0, PA=-21.0000 ADI result from IIF 1 setting reval val to 1 ===> Active Optics loop is not running

Failed two more times. result from IIF 1 setting reval val to 1 ===> Active Optics loop is not running IDL> observe

The shell RIP

Resend the preset . Failed. result from IIF 1 setting reval val to 1 ===> Active Optics loop is not running IDL> observe

Trying the same preset and point to a bright star, we could improve the psf. 8:00 preset, IS_ERI, MODE=ACTIVE, GS=0, PA=-21.0000.. Preset on axis and collimation on axis. ADI Trying to close the loop the W-Unit dind't complete the close loop process, giving many skip_frames, this cause that we could't close the loop. We could talk with Alfio in firenze and he was checking what is causing this strange effects..

We tried two time and the loop is close taking images...

8:35 preset, IS_ERI, MODE=ACTIVE, GS=0, PA=-21.0000 ADI

9:20 preset, B_CMI, MODE=ACE, GS=0, RS=0, PA=-72.0000 ADI thick clouds passing breaks the close loop.

Thick clouds, close the dome...
