LBC on 11 September 2009 UT

Nautical Twilight at 02:26 UT

We are closed due to threatening clouds.

The LBC team tried to put some new software on CMU without success.

We had again the issue of the "Runaway uiupdate.php popup in Firefox" as reported in Issue Track #984. Working on lbtmu42. Killed firefox. Ok for a while. It reappears at 3:32 UT....

It re-appears at 03:55 but apparently only if the LBC UI is displaying the House-Keeping.

We open at 03:55. T_air = 10.4 T_mirr = 11.1. mostly clear (spectroscopic).

04:03 Slewing to Pointing Star WT00200 No stars ! Clouds

04:13 Slewing to East to WT000362 Now OK

New CA = -133.4 IA=-17.4

04:24 Let's Collimate: DOFPIA

LBCB seeing est. ~ 2.0" LBCR seeing est. ~ 1.6"

04:37 Sky Brightness Monitor giving V = 21.56 mag /arcsec^2 (ok it's not exactly V-band but very close).

04:38 Again DOFPIA

Again : LBCB seeing est. ~ 2.0" LBCR seeing est. ~ 1.6"

DOFPIA fails to calculate Z11 and Z22 at Blue (seeing too bad)

04:51 DOFPIA only Blue with BlueLimit = 600

Still Z11 not calculated; seeing too bad.

04:56 Testing Rotator Trajectory with two 120s exposures with both cameras

lbcb.20090911.045632.fits lbcr.20090911.045630.fits

Images are heavily trailed due to Rotator ! The guide compensated a little on the right side of the array. Call Michele to patch the software back.

05:09 Software patched

05:10 Testing Rotator Trajectory with two 120s exposures with both cameras

lbcb.20090911.051031.fits lbcr.20090911.051025.fits

Trailed but..oops, we were not tracking after PCS restart frown, sad smile

05:14 Repeat the above test again

Tracking again faulty. Change Coordinates from LBC UI and re-send preset. Now ok.

05:18 Testing Rotator Trajectory with two 120s exposures with both cameras

lbcb.20090911.051821.fits lbcr.20090911.051815.fits

Patch Successful; Trailing disappeared but seeing now around 3". We need to re-collimate.

We go on with Collimation data.

First two images at +35 Elevation. T_air 10.2 T_mirror = 10.5

08:16 Fit Curves look very good

Copying the new Collimation table on lbtmu41

Renaming the existing ones:

mv SXPMLBCCollimation.dat SXPMLBCCollimation.20090909prev.dat mv DXPMLBCCollimation.dat DXPMLBCCollimation.20090909prev.dat

and putting the freshly obtained ones:
