Ca II K Spectral Study of an Emerging Flux Region using Domeless Solar Telescope in Hida Observatory
Kenichi Otsuji, Reizaburo Kitai, Takuma Matsumoto +5
A cooperative observation with Hida observatory and Hinode satellite was performed on an emerging flux region. The successive Ca II K spectro-heliograms of the emerging flux region…
Temporal power spectra of the horizontal velocity of the solar photosphere
Takuma Matsumoto, Reizaburo Kitai
We have derived the temporal power spectra of the horizontal velocity of the solar photosphere. The data sets for 14 quiet regions observed with the Gband filter of Hinode/SOT are…
Spectroscopic Studies of Limb Spicules. I. Radial and Turbulent Velocities
Makiko Shoji, Takara Nishikawa, Reizaburo Kitai +1
We made high-resolution spectroscopic observations of limb-spicules in H-alpha using the Vertical Spectrograph of Domeless Solar Telescope at Hida Observatory. While more than half…
Spicule Dynamics over Plage Region
Tetsu Anan, Reizaburo Kitai, Tomoko Kawate +14
We studied spicular jets over a plage area and derived their dynamic characteristics using Hinode Solar Optical Telescope (SOT) high-resolution images. The target plage region was…
Observations of Chromospheric Anemone Jets with Hinode SOT and Hida Ca II Spectroheliogram
Satoshi Morita, Kazunari Shibata, Satoru Ueno +3
We present the first simultaneous observations of chromospheric "anemone" jets in solar active regions with Hinode SOT Ca II H broadband filetergram and Ca II K spetroheliogram on…
