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. 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.
