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…
Spectro-Polarimetric Observation of an Emerging Flux Region: Triggering Mechanism of Ellerman Bombs
H. Watanabe, R. Kitai, K. Okamoto +6
High spatial resolution observation of an emerging flux region (EFR) was done using a vector magnetograph and a H-alpha Lyot filtergraph with Domeless Solar Telescope at Hida Obser…
Umbral Fine Structures in Sunspots Observed with Hinode Solar Optical Telescope
Reizaburo Kitai, Hiroko Watanabe, Tahei Nakamura +15
High resolution imaging observation of a sunspot umbra was done with Hinode Solar Optical Telescope (SOT). Filtergrams in wavelengths of blue and green continuum were taken during…
Small Scale Magnetic Flux Emergence Observed with Hinode/Solar Optical Telescope
Kenichi Otsuji, Kazunari Shibata, Reizaburo Kitai +14
We observed small scale magnetic flux emergence in a sunspot moat region by the Solar Optical Telescope (SOT) aboard the Hinode satellite. We analyzed filtergram images observed in…
