Abstract:
We present the spectrum of SN 2023ixf observed at 03:19:22.4 UTC on 23 May 2023 (MJD = 60087.138) using the Dark Energy Spectroscopic Instrument (DESI) at the 4m Mayall Telescope at Kitt Peak National Laboratory. The spectrum was recorded at medium resolution from 360-980nm with an exposure of 173s taken at twilight.

We present the spectrum of SN 2023ixf observed at 03:19:22.422069248 UTC on 23 May 2023 (MJD = 60087.138) using the Dark Energy Spectroscopic Instrument (DESI) at the 4m Mayall Telescope at Kitt Peak National Laboratory. The spectrum was recorded on a single fiber pointing into one of the DESI three-arm spectrographs spanning 360-980nm.  The 173 second exposure was taken during astronomical twilight (see first comment). Fiber #3259 on DESI tile 83365.

Comments:

- The fiber effective exposure time is 27.79 seconds normalized to DESI’s fiducial conditions in dark time.

- Emission lines previously seen in the Liverpool Telescope 5-19-23 spectrum have greatly decreased in strength and now only H-alpha, H-beta, and He II 4868 are seen clearly.

- Weak Na I D is seen at the velocity of M101.
