1 Otero, Sebastian Alberto Blend of Gaia DR3 4063389325191009920 (G= 17.3) and Gaia DR3 4063389329495671808 (G= 17.5; 0.6" to the W). Gaia DR3 4063389329495671680 (G= 17.9) is 1.3" to the NNE. Identification is based on variability detection in 2022yCat.1358....0G, but that variability is most likely spurious and caused by the close companion so the actual ID remains to be confirmed.
