Scientific paper

X-ray images from the Yohkoh satellite, obtained following occurrences of limb flares sometimes show coronal fan-like structures extending above a growing post-flare loop system. We show one such event observed in AR 7270 on the east limb of the Sun on 28/29 August 1992. We suggest that these rays are `ministreamers,' formed as a result of the re-structuring of the corona following the occurrence of a flare-associated CME. Synoptic maps of the solar wind density, constructed from a tomographic analysis of interplanetary scintillation (IPS) measurements, show enhanced scintillation matching the position of AR 7270 if we assume a radial outflow at a reasonable slow solar wind speed of 400 km s-1. From this agreement we argue that outflow of mass occurs from the active region into interplanetary space.
