Abstract: In this study, we analysed the close binary open clusters CWNU2666 and HSC224. They are in close spatial proximity, using photometric and astrometric data from the Gaia DR3. Most likely member stars were used with a membership probability (P \geq 0.5) were identified 106 and 146, the mean proper motion components (μ_α cos δ, μ_δ) obtained as (0.646 ± 0.155, -0.769 ± 0.124) and (0.665 ± 0.131, -0.728 ± 0.107) mas yr^-1, isochrone distances (d_iso) as 1885 ± 44 and 1866 ± 29 pc, and ages (t) as 160 ± 15 and 140 ± 15 Myr, for CWNU 2666 and HSC 224, respectively.
