	The name "Alrumh" (or similar) was suggested to WGSN in 2026, as there is a Chinese asterism of The Lance in the same area of the sky (but not exactly the same stars). The ~~idea~~ was to give the name "The Lance" in two different languages to two stars in the area pointing to a random coincidence of similar names in the sky. The Lance is a longish object, covering an area - and it is held by a person (whose constellation covers an even larger area). The two stars identified with the al-Rumh (~~eps~~, eta Boo) ~~are both named but perhaps a dimmer~~ star ~~in that area~~ (in ~~between~~ the ~~two?~~) ~~could~~ be ~~used~~ to ~~resemble~~ the ~~historical constellation?~~		The name "Alrumh" (or similar) was suggested to WGSN in 2026, as there is a Chinese asterism of The Lance in the same area of the sky (but not exactly the same stars). The proposal was to give the name "The Lance" in two different languages to two stars in the area pointing to a random coincidence of similar names in the sky. The Lance is a longish object, covering an area - and it is held by a person (whose constellation covers an even larger area). The two stars identified with the al-Rumh (epsilon, eta Boo) already had IAU WGSN-adopted names (Izar and Muphrid, respectively). On April 15, 2026, WGSN adopted the name '''Alrumh''' for the star 34 Boo (HR 5490, HD 129712, HIP 71995, W Boo), which is part of the ''Al-Rumḥ'' asterism, and in the vicinity of Izar.

			Alrumh (34 Boo) is a red giant star with spectral type M3-III (Keenan & McNeil 1989), and from its trigonometric parallax measured by the ESA Gaia mission one estimates its distance to be approximately 181 parsecs (Gaia Data Release 3). The star has a wide range of reported average V magnitudes: V=4.26 (Hipparcos, ESA 1997), V=4.81 (Bright Star Catalog 5th ed., Hoffleit & Warren 1991). This reflects the star's status as semi-regular variable star (also designated W Bootis) with photometric amplitudes of tenths of a magnitude and periodicity ranging from ~25 days to ~50 days. Further documentation of the star's complex photometric variability can be found in the study by Percy & Desjardins (1996; https://ui.adsabs.harvard.edu/abs/1996PASP..108..847P/abstract).
