02:50 TO opens the dome and starts collimating

• Seeing = 1.3"-1.5"
• seeing improved between second an third integrations = 1.2''
• during the third integration seeing get worse again = 1.4''-1.6''
• during the last integration seeing is getting better = 1.2''-1.3''

04:30 start acquisition of FEIGE34 (red & dual grating) mods1r.20150317.0023-0024

04:50 dofpia (parallel) on the red channel

05:00 the seeing is dropping to 1''

- FIORE B -

05:11 slewing to FioreB

06:42 Launched LBC red OB in parallel mode

- NASCIMBENI -

06:53 Acquisition of WASP39 field of Nascimbeni mods1r.20150317.0039-

• seeing 1.2'

06:53 Acquisition stopped: Rotator Unwrap

06:58 Acquisition of WASP39 field of Nascimbeni mods1r.20150317.0040-41

• seeing 1.2'

07:13 execMODS mods.wasp39.obs mods1r.20150317.0042-4

• seeing 1.2'
• seeing 1.6'' during the 10th exposition

07.27 launched wasp39_lbc.ob

• wasp39 is saturated, we defocus more
• seeing 1.6''
• coma problems with LBC, TO tries corrections
• run dofpia again
• 07:46 seeing 1.7''
• not able to reach the requested counts, so we change the exposure time (t_new=t_old*0.60)
• 08:47 seeing = 1.4''

09.15 Clouds are passing. MODS Guiding and LBC images are gone. We keep on with MODS.

09.25 We stopped acquiring with LBC.

10.05 We stopped acquiring with MODS.

10.10 Resuming acquisition with MODS.

10:45 Pausing the acquisition

11:00 resuming again the acquisition

11:07 Pausing again the acquisition, no spectra in the slits

11:49 it's too cloudy. The TO closes the dome so we can run MODS calibrations.

12:02 We run MODS calibrations
