Observers: Pierre-François Léget, Nicolas Chotard & Marine Ducrot TAT: Nancy Elias-Rosa, Joe Polshaw, Stefan Taubenberger Photometric. No sign of clouds all night and the seeing is consistently around 0.5". ---- CALIBRATIONS: - 19:00UT - In the control room. Weather looks good. - 21:00UT - 1x PESSTO_bias & 1x PESSTO_calib PRE-OBSERVATIONS: - 23:45UT - Sunset - 00:00UT - Skyflats: UVi - 00:20UT - Focussing & image analysis - 00:40UT - SPECTROSCOPIC STANDARD: VMA2. Seeing 0.6", Airmass 1.24 - 00:55UT - PHOT STD: PG0231 (UgBVRriz): Seeing 0.6", Airmass 1.25 SCIENCE-OBSERVATIONS: - 01:10UT - ASASSN-14jb: Follow up, 2100s gm13 spectrum. Seeing 0.6", Airmass 1.6 - 01:55UT - OGLE-2014-SN-189: Classification. Seeing 0.5", Airmass 1.45. - Took a spectrum but hard to classify with SNID. - 02:20UT - OGLE-2013-SN-100: Photometry. 9x200s in each BV band. Seeing 0.5", Airmass 1.45 - 03:30UT - TPhE: Standar star. Photometry. Seeing 0.4", Airmass 1.5. - 03:45UT - GD71: Standar star. Spectro. Seeing 0.6", Airmass 1.5. - problem during the exposure which didn't start. Got a bit late at this point. - Apparently because of some electric problem that they had during the day. - 04:20UT - LSQ14gie: Classification. Seeing 0.5", Airmass 1.1. - Bright target on the edge of a galaxy. - Most likely a pre-maximum (-1/2 days) normal SN Ia according to SNID, with a redshift of 0.073 - 05:00UT - LSQ14gfb: Follow up spectro. Gm13. Seeing 0.4", Airmass 1.3. - Same problem as earlier, starting the exposure a bit later than expected - 07:30UT - ASASSN-14ko: Follow up.
