Resumen:
We present the results of speckle interferometric measurements of binary stars performed in November, 2008 with the I m telescope at the Observatorio Astronomico Nacional of Tonanzintla (Puebla, Mexico). The data include 175 position angle and separations measured for 163 systems. The measured angular separations range from 0.15 '' to 4.00 ''. The maximum magnitude of the brighter components is equal to 9.32. The mean error in the separation measurement is 0.03 '' and in the position angle is 1 degrees. The majority of position angles were determined with the usual 180 degrees ambiguity, and some of them were corrected by comparison with observations performed by other observers.
