The plage region is located 200${}^{\\prime\\prime}$ east of the flare arcade. The plage region has a small transient coronal hole. The transient coronal hole is strongly affected by an X-class flare, and upflows are observed at its boundary. Multi-wavelength spectral observations allow us to determine velocities from the Doppler shifts at different temperatures. Strong upflows along with stationary plasma have been observed in the Fe XV line 284.2 Å (log$T/$ K $=6.3$) in the plage region. The strong upflows reach almost 150 km s$^{-1}$, which was estimated by a two-component Gaussian fitting. On the other hand, at a lower corona/transition region temperature (He II, 256.3 Å, log$T/$ K $=$ 4.9), very weak upflows, almost stationary, have been observed. We find that these upflow velocities clearly depend on the temperature with the hottest line, Fe XV, showing the fastest upflow velocity and the second-highest line, Fe XIV, showing the second-highest upflow velocity (130 km s$^{-1}$). All velocities are below the sound speed. The trend of the upflow dependence on temperature dramatically changes at 1 MK. These results suggest that heating may have an important role for strong upflow.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420001326209703424","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"40547965"},{"@type":"NRID","@value":"1000040547965"},{"@type":"NRID","@value":"9000014612722"},{"@type":"NRID","@value":"9000279645484"},{"@type":"NRID","@value":"9000414093069"},{"@type":"NRID","@value":"9000242559934"},{"@type":"NRID","@value":"9000415345102"},{"@type":"NRID","@value":"9000014151535"},{"@type":"NRID","@value":"9000244901697"},{"@type":"NRID","@value":"9000415345090"},{"@type":"NRID","@value":"9000334737564"},{"@type":"NRID","@value":"9000243709111"},{"@type":"NRID","@value":"9000018324808"},{"@type":"NRID","@value":"9000279645459"},{"@type":"NRID","@value":"9000333085884"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0138421"}],"foaf:name":[{"@value":"Shinsuke Imada"}],"jpcoar:affiliationName":[{"@value":"1National Astoronomical Observatory of Japan, 2-21-1 Osawa, Mitaka, Tokyo 181-8588 shinsuke.imada@nao.ac.jp"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011145074409478","@type":"Researcher","foaf:name":[{"@value":"Hirohisa Hara"}],"jpcoar:affiliationName":[{"@value":"1National Astoronomical Observatory of Japan, 2-21-1 Osawa, Mitaka, Tokyo 181-8588 shinsuke.imada@nao.ac.jp"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011145074409472","@type":"Researcher","foaf:name":[{"@value":"Tetsuya Watanabe"}],"jpcoar:affiliationName":[{"@value":"1National Astoronomical Observatory of Japan, 2-21-1 Osawa, Mitaka, Tokyo 181-8588 shinsuke.imada@nao.ac.jp"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011145074409477","@type":"Researcher","foaf:name":[{"@value":"Suguru Kamio"}],"jpcoar:affiliationName":[{"@value":"1National Astoronomical Observatory of Japan, 2-21-1 Osawa, Mitaka, Tokyo 181-8588 shinsuke.imada@nao.ac.jp"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011145074409474","@type":"Researcher","foaf:name":[{"@value":"Ayumi Asai"}],"jpcoar:affiliationName":[{"@value":"2Nobeyama Solar Radio Observatory, Minamisaku, Nagano 384-1305"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011145074409476","@type":"Researcher","foaf:name":[{"@value":"Keiichi Matsuzaki"}],"jpcoar:affiliationName":[{"@value":"3Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency, Kanagawa, 3-1-1 Yoshinodai, Sagamihara, Kanagawa 229-8510"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011145074409473","@type":"Researcher","foaf:name":[{"@value":"Louise K.
