Further Soft X-ray Images of the Sun

Abstract

ON December 17, 1964, at 03 h 35 m U.T. the firing of the second, three-axis stabilized Skylark research rocket occurred at Woomera. It carried an X-ray pinhole camera, a second version of the apparatus which produced the soft X-ray image of the Sun discussed in an earlier communication¹. Part of the negative obtained from this flight is reproduced in Fig. 1. Table 1 gives details of the filters and the pinholes used to obtain these images.
