We have studied coronal soft X-ray (SXR) arcades around filament channels, as observed with the Yohkoh Soft X-ray Telescope (SXT). We have found about a dozen events (1991–1993). Comparisons with Hα filaments have revealed an association between some SXR structures and filaments. These bright thread-like SXR structures (often) appear to be parallel to and co-spatial with Hα filaments. The SXR structures are occasionally maintained for days, although transient brightening of axial structures is more common.
