Night Report 2015-01-12

Observers: Christoffer Fremling, Anders Nyholm
TAT: Annalisa de Cia, Morgan Fraser


Sky was not completely photometric. Tonight we focused on EFOSC2 Spectroscopy, we ended up with a slight emphasis on classifications

CALIBRATIONS:

- 20.00UT: 1x PESSTO_bias
- 20:20UT: 1x PESSTO_calib
- 23:47UT: Sunset

SCIENCE-CONCLUSIONS:

with EFOSC:

Followup
- ASASSN-14il, Gr11+Gr16, good signal
- LSQ14gqk, Gr13 most likely a Ib and not Ic , mostly Ibs in Gelato, and looks like He at 6678 and 7065
- PSNJ09, Gr13 faint signal, but spectrum looks useable

Classification
- ASASSN-15al, Ia +3 z=0.03
- OGLE-009, IIp ~+40d
- ASASSN-15aj, Ia +3 z=0.01
- LSQ15bi, Ia -5, z=0.037
- LSQ15y, Ia +6d, z=0.068
- LSQ15bb, Ia-91bg +3d z=0.079 in SNID, Ia-norm in Gelato
- PSNJ13, IIP ~+40d z=0.015
- MASTER-J1503, Blue continuum, perhaps IIn?
- LSQ15bo, Ia +6d, z=0.049 SNID
