GILLI	SDSSJ1048	r, i , z	1hr	20 images with average seeing =1.1" but clouds - Telescope loosing focus - lost images - OB repeated several times - PROGRAM FINISHED
SOLLIMA	Pal4Control	g, r	1hr	Blue Seeing =1.2" - 3 red images out of focus almost to redo

Details

01:50 Sky flats Uspec + Y

02:05 Sky flats Bbes + rsloan

02:30 dofpia

02:40 Standard SA101 (Seeing 1.3")

02:53 SDSSJ1030 focus OB

02:55 dofpia

03:00 lbcrangebal. Images of rangebal were elongated!

03:05 dofpia,/x2 again

03:08 ri2-1.ob

03:40 OB aborted after 6th image because blue images start to be elongated again.

• dofpia, /X2

03:44 ri2-1.ob - repeat to obtain last 3 images

04:00 SDSSJ1048 focus OB

04:02 dofpia,/x2

04:08 SDSSJ1048 focus OB

04:12 dofpia,/x2

04:16 ri3-1 SDSS J1048

04:47 OB stopped due to bad collimation in the blue channel

04:47 dofpia,/x2

04:55 ri3-1 SDSS J1048 (random pattern changed) getting 4 more images. dimm seeing 1.2

05:10 OB stopped still bad collimation on the blue side

05:10 dofpia,/x2

05:16 rz3-1 SDSS J1048 (clouds coming close)

5:31 OB aborted because focus non blue is terrible - clouds passing through background on images very high (30000-40000counts)

• dofpia,/X2

5:35 rz3-1 -repeat OB

5:58 the last 2 images are completely saturated because of clouds... even at the beginning of he OB the background counts were fairly high

6:10 stars start appearing again but they are out of focus - abort OB

06:12 dofpia,/X2

06:20 rz3-1 -repeat OB

06:45 dofpia,/X2

06:51 rz3-1 -repeat OB

07:10 Loosing focus, images not saved in the archive.

07:11 dofpia,/X2

07:16 rz3-1 -repeat OB

07:46 Loosing focus. It's enough with Gilli

07:48 Focus PAL4 Control

07:50 dofpia,/X2

07:55 PAL4ControlFocus

07:58 lbcrangebal

08:00 Pal4control_a

08:17 OB aborted because the red image is completely out of focus.

• the first two images were - one drifting out of focus ... the second in focus!!! - third completely out of focus...
• dofpia,/2X

08:22 Pal4control_a_2off

08:50 dofpia,/X2

08:54 Pal4control_b

09:09 Pal4control_b Repeating the ob since the red camera didn't started.

09:33 very bad seeing (1.7)

09:47 OB finished - should be repeated

09:53 dofpia,/X2

10:04 Focus OB Nonino

10:06 lbcrangebal

10:08 dofpia,/X2

10:22 EGS_BR_1

10:46 EGS_BR_2 (blu telescope jumped)

10:53 dofpia,/X2

10:58 EGS_BR_2

11:20 ABORT (when 12/15) because the blue was out of focus and the last image seemed to have a jump

• red channel looks fine
• dofpia,/X2
• repeat BR_2 next time if necessary...

11:26 EGS_BR_3

11:53 dofpia,/X2

12:00 EGS_BR_4

12:04 EGS_BR_4 stopped due to elongated stars

12:12 dofpia,/X2

12:16 dofpia,/X2

12:26 EGS_BR_3 (two exposures only)

12:33 Skyflat_gr_pa180

12:45 END OF NIGHT
