%X Two identical X-ray experiments were flown on Skylark rockets from Woomera, Australia, during April 1967. Sco XR-l and Cen XR-2 were observed on both flights. The Cen XR-2 flux was (1-5±0'1) X 10-7 erg cm-2 sec-1 (2-8 keY) when first observed but had decreased to (l·0±0·1) X 10-7 erg cm-2 sec-1 and had become softer by the second flight. An X-ray flux from the Earth was observed and found to be due to solar X-rays reflected in the atmosphere.
