In August 2026, the name Magur was proposed and adopted by the IAU WGSN for the star HR 6862 (HIP 90037, HD 168592) , a star with apparent V magnitude 5.09 in the constellation Corona Borealis. This naked eye star was selected as it is located at the front tip of the depicted river barge asterism. Magur is a red giant star with spectral type K4/5III (Houk 1982) about 148 parsecs away, based on its Gaia DR3 parallax (Bailer-Jones et al. 2021, Gaia Collaboration 2023).Fetherolf et al. (2023) reports the light curve of the star measured by the NASA TESS mission revealed a periodicity of 4.9851 days with an amplitude of about 1 millimagnitude. Thus far, no companions have been reported for this star.
