Polarization Calibration of the Solar Optical Telescope onboard Hinode

Rotation of sunspots in active region NOAA 10930

“…The Spectropolarimeter Suematsu et al, 2008;Ichimoto et al, 2008) aboard Hinode (Kosugi et al, 2007) satellite makes spectropolarimetric measurements with a spatial sampling of 0.3 00 . The I, Q, U and V Stokes profiles are obtained in Fe I 6301.5 Å and 6302.5 Å lines.…”

Nonlinear force-free field extrapolation of the coronal magnetic field using the data obtained by the Hinode satellite

“…[10] In this paper, we continue the work of and apply the upward boundary integration computational scheme of DBIE method for NLFFF extrapolation to the photospheric vector magnetograms acquired by the Spectro-Polarimeter (SP) of the Solar Optical Telescope (SOT) [Tsuneta et al, 2008;Suematsu et al, 2008;Ichimoto et al, 2008;Shimizu et al, 2008] aboard Hinode satellite [Kosugi et al, 2007]. The Hinode satellite, which was formerly called Solar-B and was launched in September 2006, can obtain high-quality photospheric vector magnetograms of solar active regions by SOT-SP instrument, and the simultaneous coronal loop images of the same active regions in soft X-ray band by the X-Ray Telescope (XRT) Kano et al, 2008] as well as in extreme ultraviolet band by the EUV Imaging Spectrometer (EIS) [Culhane et al, 2007].…”

“…The magnetic field data of an X3.4 flare on 12 December 2006 was obtained at 2030 UT from spectropolarimeter data of Hinode/Solar Optical Telescope [Kosugi et al, 2007;Tsuneta et al, 2008;Suematsu et al, 2008;Ichimoto et al, 2008;Shimizu et al, 2008]. The spatial resolution of this data is about 0.3 arcsec.…”
