Psi2 Lupi is the blue star in the centre of this image. Nearby to the northwest is Psi1 Lupi which, despite its shared 'Psi' designation, is an unrelated yellow star considerably closer to the Sun than Psi2. (The star to the immediate east of Psi2 is blue HR 5860, which is also unrelated to the two 'Psi' stars of Lupus.) Imagery provided by Aladin sky atlas
