Journal Article
Observation of a Solar Flare at the Limb with the Yohkoh Soft X-Ray Telescope (Initial Results from Yohkoh)
TL;DR: In this paper, a long-enduring soft X-ray flare at the solar limb was well observed by the Yohkoh spacecraft from the preflare stage through the postflare phase.
Journal ArticleDOI
Hinode Calibration for Precise Image Co-alignment between SOT and XRT (November 2006 -- April 2007)
