We present the first results from the Early Planet Formation in EmbeddedDisks (eDisk) ALMA Large Program toward Oph IRS43, a binary system of solarmass protostars. The 1.3 mm dust continuum observations resolve a compact disk,~6au radius, around the northern component and show that the disk around thesouthern component is even smaller, <~3 au. CO, 13CO, and C18O maps reveal alarge cavity in a low mass envelope that shows kinematic signatures of rotationand infall extending out to ~ 2000au. An expanding CO bubble centered on theextrapolated location of the source ~130 years ago suggests a recent outburst.Despite the small size of the disks, the overall picture is of a remarkablylarge and dynamically active region.
