Abstract (from CDS):

We present the discovery of CWISE J151044.74-524923.5, a wide low-mass companion to the nearby (∼24.7 pc) system L 262-74, which was identified through the Backyard Worlds: Planet 9 citizen science project. We detail the properties of the system, and we assess that this companion is a mid-L dwarf, which will need to be verified spectroscopically. With an angular separation of 74.″3, we estimate a projected physical separation of ∼1837 au from the central system.
