Speckle interferometric measurements of binary stars. IV Seventy-three measurements of 61 binary stars by means of speckleinterferometry with the Mayall 4-m telescope are presented. The measuredseparations range from 0.031 to 1.368 arcsec. Observations are presentedfor the three previously unresolved spectroscopic binaries: HR 5472, HR6237, and HR 8264, as well as for 18 additional interferometricbinaries.
