S/2003 J 24 (temporarily designated EJc0061) is a moon of Jupiter, discovered by Scott S. Sheppard et al. in 2003. It was independently found by amateur astronomer Kai Ly, who reported it on June 30, 2021.^[1]^[2] It was formally announced on 15 November 2021 in the MPEC.^[3]

Ly had previously recovered four "lost" moons of Jupiter in 2020: S/2003 J 23, S/2003 J 12, S/2003 J 4, and S/2003 J 2.^[4]

S/2003 J 24 orbits Jupiter at an average distance of 23,088,000 km (0.15433 AU) in 715.4 days, at an inclination of 162° to the ecliptic, in a retrograde direction and with an eccentricity of 0.25.

It belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 Gm and at an inclination of about 165°.
