Summary

Clouds cleared off enough to open by 3 UT.

Got some final wake-up observations with LBC and identified a bug in the code. Clouds got too thick for LBC, so switch to active optics calibrations with AGW1 at 6:30. Made good progress on crosstalk with AGW1 and zernike calibrations with MODS1 once clouds thinned out. Switched to MODS1 observations at 10:10 and got a standard. Closed by humidity an hour later.

Preparations

James and Conrad fixed both LBC-Red Shutter and the LUCI1 communications issues.

Michele and Dan gave us a new version of ECS and ECSGUI.

Details

Had a visit by Eagle Gamma -- http://eaglegamma.com -- and showed him the telescope around sunset. It took him 6 hours to bicycle up from the basecamp. Humidity has been sitting at 92% for a while.

02:55 Humidity is dropping so we will try to open.

Open

03:03 Open to a few clouds and rapidly dropping humidity. 73% T=10.7, D=6.0, wind light out of SE. Chamber is close to ambient, but mirrors are still 3-4 degC warm.

OSU monitor N6503

03:05 OSU_monitor_N6503focus.ob

03:09 DOFPIA, /FIRST

03:17 OSUmonitorN6503.ob -- telescope is drifting so that guiding is struggling to keep up -- why? The rotator speed is wrong at EL=51. Stopped OB after the first image.

03:25 Switch PCS back to the old pointing kernel PCS.2014C

03:28 OSUmonitorN6503.ob again

Call Michele

Call Kellee

Could it be a hidden rotator error not reported on UI?

03:39 Turn off / on LBC software crashed twice during turn on

03:40 Back to PCS.tpk2.3 the new pointing kernel

03:46 OSU_monitorN6946.ob without focussing - problem persists

Kellee sees in the log that LBC thinks it doesn't have a rotator trajectory.

03:51 lbckill/lbcstart to get rotator diagnostics (flag in config file)

03:53 OSU_monitorN6946.ob without focussing

03:59 lbckill/lbcstart to get version of 2-Sep-2014 lbc software

04:02 OSU_monitorN6946.ob without focussing -- rotator is OK

04:08 OSU_monitor_N6503focus.ob

04:09 DOFPIA blue struggling with focus convergence

04:17 OSUmonitorN6503.ob -- and blue guide star looks not well focussed. SX Primary Actuator 423 is disabled. Image has a bit of trefoil. Red images are beautiful.

Arp314 Dithered Observation

04:33 Arp314focusdual

04:36 DOFPIA (stopped manually at EL=38)

04:42 Arp314dual for dithered deep observation -- (as deep as you can with a gibbous moon) -- seeing is rather puffy down here at EL=38. shutter closed on red from OB.

04:46 replayed editted Arp314dua

04:49 DOFPIA

04:51 Arp314dual_back.ob was OK until some clouds near the moon drifted across us about halfway through the OB.

05:21 Arp314_dual_rotate_VI PA=90 - still fighting thin clouds -- I guess we'll call them sky flats with 55 counts in Blue.

NS 2060 Chiron

05:32 Hijacked LBC preset to Chiron - rate ~8 arcsec per hour - loads of moonlit clouds, but these are short exposures.

05:38 WT10_323 in a part of the sky where there is less cloud.

05:39 SX Primary Panics during preset - why?

05:55 WT10_323

Clear Active Optics

06:00 DOFPIA, /FIRST -- too much cloud

DOFPIA needs to wait slightly longer for the next OB when no pupils are found. But, shouldn't DOFPIA have exited when no pupils found? The exit only works on the first iteration. I added 2 sec of WAIT to dofpia.pro before it plays the OB.

Reconstructor Tests

06:17 Reconfigure to LUCI1 as too many clouds for LBC. Doug is on the Polycom from home 3-wayed to N525.

06:39 LUCI1 on left for AGW1 and LBC-Red on right.

ACQUIRE

06:43 ACTIVE preset to BS9188 with Doug's new reconstructor -- failed co-pointing limit even with pseudomono mode Can't do pseudo mono when authorized as ARGOS -- targets are too far apart?
