The 2SPOT (Southern Spectroscopic Project Observatory Team) has produced a spectrum showing Balmer lines in very broad emission and a very red spectrum on the continuum.
Spectra taken in Chile with a 305mm f/4 Newton equipped with an Alpy 600 spectrograph (R=570): 5 spectra of 600s each taken at 15.979-07-2023 (Mid JD = 2460141.4790)
Another spectrum is in progress using an echelle spectrograph (R=11000).
