Co-operative Observation with XDT-Rocket
31-Jan-1998.

---

This observation was hold in order to support the XUV-Dopper-Telescope on boarded the rocket made by High-energy-solarphysics-team of National Astronomical Observatory.
The XDT can observe filtering images around a coronal emission line (FeXIV 211A) of the solar full disk ( Example ). Thus, they can obtain the coronal velocity field along the line of sight of the full disk.
Besides our Kwasan Observatory, this observation was co-operated by many ground-based observatories, such as Hida Obs., Norikura Corona Obs., Mitaka Obs., Nobeyama Radio Obs., Hiraiso Obs., Nishi-harima Public Obs. etc.
