摘要：

We present speckle observations of nineteen double stars and the triple star 2 Cam. Angular separations, absolute position angles and relative photometry result from these observations. The angular separation is derived from the power spectrum. The position angle and the relative photometry are determined by two recent techniques: the cross-correlation between the speckle images and their square, and the ratios of twofold probability density functions of the images.
