Abstract In this paper we present multiband speckle interferometric measurements of double stars performed at the 2.1 m telescope Observatorio Astronómico Nacional, San Pedro Mártir, México. We focused our efforts on objects from Washington Double Star Catalog that were observed during five runs allocated in 2018 and 2019. report here 2101 astrometric 2027 photometric 631 pairs, with angular separations ranging 0.″05 to 6.″09, including 1622 smaller than 1″, a magnitude difference up 5.99...
