Magnetic Structure of Umbral Dots Observed with Hinode Solar Optical Telescope
Hiroko Watanabe, Reizaburo Kitai, Kiyoshi Ichimoto +1
High resolution and seeing-free spectroscopic observation of a decaying sunspot was done with the Solar Optical Telescope aboard Hinode satellite. The target was NOAA 10944 located…
Chromospheric Anemone Jets as Evidence of Ubiquitous Reconnection
Kazunari Shibata, Tahei Nakamura, Takuma Matsumoto +19
The heating of the solar chromosphere and corona is a long-standing puzzle in solar physics. Hinode observations show the ubiquitous presence of chromospheric anemone jets outside…
Magnetic Landscape of Sun's Polar Region
S. Tsuneta, K. Ichimoto, Y. Katsukawa +11
We present the magnetic landscape of the polar region of the Sun that is unprecedented in terms of high spatial resolution, large field of view, and polarimetric precision. These o…
Magnetic Flux Loss and Flux Transport in a Decaying Active Region
M. Kubo, B. W. Lites, T. Shimizu +1
We estimate the temporal change of magnetic flux perpendicular to the solar surface in a decaying active region by using a time series of the spatial distribution of vector magneti…
Disintegration of Magnetic Flux in Decaying Sunspots as Observed with the Hinode SOT
M. Kubo, B. W. Lites, K. Ichimoto +8
Continuous observations of sunspot penumbrae with the Solar Optical Telescope aboard \textit{Hinode} clearly show that the outer boundary of the penumbra fluctuates around its aver…
On-orbit Performance of the Solar Optical Telescope aboard Hinode
K. Ichimoto, Y. Katsukawa, T. Tarbell +8
On-orbit performance of the Solar Optical Telescope (SOT) aboard Hinode is described with some attentions on its unpredicted aspects. In general, SOT revealed an excellent performa…
