Observers: Pierre-François Léget, Nicolas Chotard & Marine Ducrot TAT: Joe Anderson & Annalisa de Cia The wind was quite high at the begining of the night (11.5m/s). Observations to the north were not possible. It went down below 10 during the first observation. ---- CALIBRATIONS: - 20:00UT: 1x PESSTO_calib, 1x PESSTO_bias - 23:50UT: Sunset PRE-OBSERVATIONS: - 00:00UT: We are ready to observe with SOFI- 00:20UT: Focusing and image analysis SCIENCE-OBSERVATIONS: SOFI observations: - 00:40UT: ASASSN-14jb, BG spectrum, Airmass (begining: 1.3, end: 2.3), Seeing (average: ~1.14") - 04:10UT: GD71 Flux standard Airmass 1.42, Seeing ~1.2". Wind 12.5m/s Observations to the north/east were not possible - Because of wind we can't do the Spectroscopic standard star GD71 - 04:50UT: LSQ14gjn classification Airmass 1.29 Seeing 1.04". A bit cloudy and probably problem of galactic substraction. No determined. - 05:10UT: LTT3864 Spectroscopic standard star (gm11, gm13, gm16) Airmass 1.56 Seeing 0.89" - 05:35UT: TPhE: Standar star. Photometry. Not done, too low in the sky - 05:40UT: PESSTOESO154-G10 gm11+gm16 spectra Airmass 1.58 Seeing 0.85" - 06:30UT: RU149 Photometric standard. Airmass 1.14 Seeing 1.11" - 06:40UT: ASASSN-14ha gm11+gm16 spectra Airmass 1.55 Seeing 1.1" - 07:40UT: ASASSN-14ha photometry U-band Airmass 1.60 Seeing 1.11" - 08:55UT: OGLE-2014-SN-189 photometry R-band Airmass 1.35 Seeing 1.05" - 08:10UT: L745a Spectroscopic standard star (gm11, gm13, gm16) Airmass 1.25 Seeing 0.9" - 08:35UT: RU149 Photometric standard. Airmass 1.43 Seeing 1.00". Exposure aborted before its end. - 08:42UT: electronic problem with EFOSC. Night aborted. POST-OBSERVATIONS: No post observations due to the electronic. SCIENCE-CONCLUSIONS: with SOFI: ASASSN-14jb, BG spectrum SN2013hx in K-band with EFOSC: LSQ14gjn for classification PESSTOESO154-G10 gm11+gm16 spectra ASASSN-14ha gm11+gm16 spectra ASASSN-14ha photometry in U-band OGLE-2014-SN-189 photometry in R-band |
