Hi Robin, this is a very quick check (11 june) with Lhires III and 150 l/mm grating. Only 35 mins integration in binning 4x4. Target is faint and spectrum noisy. Anyway I try to extract the profile.
The 2d spectrum and slit view:
Spectral profile calibrated (wavelength & relative intensities):
Gelato, the system provides automatic recognition, provides in first instance an analogy with type IIn SN2009au at 4 days age:
Most items in report are SN II type in early stage:
I perform observation and data reduction very quickly and hope I have not made mistakes. Target profile is very poor in features (perhaps it is normal in the early days of a SN event) but it could also be for low SNR or other. It would be good to have a further confirmation.
