A measurement of the spatial distribution of the X-ray flux from the Perseus cluster of galaxies is reported. The measurement was made with a one-dimensional X-ray telescope carried by an Aerobee sounding rocket on February 8, 1974. The results are compared with previous X-ray observations and optical measurements of the galaxy distribution. The data show the presence of a luminous feature centered on NGC 1275, considerable emission from extended regions, and a marked asymmetry between the E-W and N-S distributions in the X-ray flux.
