report:
We obtained spectroscopy of the host galaxy of GRB 200613A (Fermi-LAT
detection: Ohno et al. GCN #27931; Fermi GBM detection: Bissaldi & Lesage,
GCN #27930; optical counterpart discovery: Kann et al. GCN #27935) with OSIRIS,
mounted on the 10.4m GTC telescope (Roque de los Muchachos Observatory,
La Palma, Spain). The observation was performed on the 18 January 2021 with
mean epoch at 00:02 UT (218.75 days after the burst) and consisted of 3x1200s
exposures with grism R1000R, covering the range between 5100 and 10100 ��.
The spectrum is characterised by a continuum that is detected over the complete
spectral range, with better SNR in the blue part of the spectrum, and has a strong
emission feature that we identify as the [OII] 3727/3729 doublet, at a redshift of
1.2280. At a similar redshift of 1.2255 we also identify absorptions due to FeII and
MgII, that allow us to confirm the redshift, which we identify as that of GRB 200613A.

Bissaldi et al., GCN #27930; Ohno et al., GCN #27931; Evans, GCN #27932)
with the Himalayan Faint Object Spectrograph and Camera (HFOSC) mounted
on the 2-m Himalayan Chandra Telescope located at IAO, Hanle, India.
Observations started on 2020-06-19 at 15:20:43 UT and we obtained 3
frames, each of 300 sec in the Bessell R-band filter under moderate sky
conditions.
The afterglow (Kann et al., GCN #27935; Pozanenko et al., GCN #27937;
Zhu et al., GCN #27943; Marshall, GCN #27944; Liu et al., GCN #27949;

visible in the stacked image. We measure a preliminary magnitude of R =
20.59 +/- 0.26 mag calibrated against the USNO-A2.0 catalogue stars. The
host contamination has not been removed in the analysis.
We thank the observing staff at IAO and CREST for helping with the
observations.
