A prediction for the location of S1 based on the family of dynamically stable orbits for S1 + C1 consistent with the nondetections in 2025 suggests that S1 will be well positioned for recovery in 2026 August. Left: predicted position in sky coordinates. The approximate orientation of the 4QPM transition boundaries at the selected example observation date is shown as a shaded region. The dashed circle marks a 0﹩\mathop{.}\limits^{^{\prime\prime} }﹩75 separation. Right: histogram of the predicted separation of S1 in 2026 August for the two orbital semimajor axis families. A dashed line marks a 0﹩\mathop{.}\limits^{^{\prime\prime} }﹩75 separation. The a < 2 au orbits constitute a greater fraction of the total number of orbits and are also favored based on photometric modeling in Section 5.
