Details

00:58 - 5 Bias monoB

01:08 - 10Bias_Bino

01:13 - stopped bias 8/10. Slew to 04:50 , +27:00 for flats

01:15 - Sky Flat Test U 0.3s (~62000)

01:18 - Sky Flat U 5x0.5s PA=0

• 1st one slightly saturated

01:22 - Sky Flat Uspec 5x0.8s PA=0

01:25 - Sky Flat B 5x0.5s PA=0

01:29 - Sky Flat B 5x1.0s PA=180

01:33 - SkyFlat V 5x2.0s PA=0

01:38 - Sky Flat V 5x5.0s PA=180

01:43 - Sky Flat r 5x10.0s PA=180

• 800 counts. Strange behavior, looks like shutter got stuck. Test with V and r fast OBs.
• Shutter seems not to be working. Try shutdown and restarting the camera.

02:00 - No way. Shutter in strange position

• Try to move with testpower and minicom.
• Succeeded.

02:20 - Exposure ok. Restart (35 min downtime, although it does not affect science time, as it happened during twilight)

02:23 - Slew to NGC 2264

02:25 - dofpia,/BlueOnly

• Usual Z7 -3000 Needed

02:28 - dofpia,/BlueOnly

• Big pupils. Z7 not applied. Also need Z4 +10000

02:32 - dofpia,/BlueOnly

• still not converging properly, sends crazy Z4=-13544
• Z4 +14000
• Z7 -2000

02:38 - try again....

• Slight problems with the guiding. After OB check the pointing
• It seems to loose focus during a single exposure. Perhaps effect of forces? We re-collimated during exposures.
