Cooperative Observation of Ellerman Bombs between the Solar Optical Telescope aboard Hinode and Hida/Domeless Solar Telescope

Matsumoto, Takuma; Shibata, Kazunari; Tsuneta, Saku +13 more

High-resolution CaIIH broad-band filter images of NOAA10933 on 2007 January 5 were obtained by the Solar Optical Telescope aboard the Hinode satellite. Many small-scale (∼1") bright points were observed outside the sunspot and inside the emerging flux region. We identified some of these bright points with Ellerman bombs (EBs) by using Hα images ta…

Hinode's Observational Result on the Saturation of Magnetic Helicity Injected into the Solar Atmosphere and Its Relation to the Occurrence of a Solar Flare

Magara, Tetsuya; Tsuneta, Saku

This paper is intended to present key features of the evolution toward the onset of a solar flare, using Hinode's observations on the photospheric magnetic field. Hinode can provide the temporal development of the photospheric field as a vector quantity, which shows that magnetic shear is initially developed in a flare-productive active region (AR…

2006 December 17 Long Duration Flare Observed with the Hinode EUV Imaging Spectrometer

Harra, Louise K.; Doschek, George A.; Hara, Hirohisa +5 more

A GOES C-class long-duration flare that occurred near the west limb on 2006 December 17 was observed with the Hinode EUV Imaging Spectrometer (EIS) in raster-scan observations. Cusp-shaped arcades are prominent in the spectroheliogram of the CaXVII emission line at 192.86Å. Spatial relationships between hot flare loops with a cusp apex and cool po…

Vertical Temperature Structures of the Solar Corona Derived with the Hinode X-Ray Telescope

Golub, Leon; Hara, Hirohisa; Shimojo, Masumi +12 more

We obtained temperature structures in faint coronal features above and near the solar limb with the X-Ray Telescope aboard the Hinode satellite by accurately correcting the scattered X-rays from surrounding bright regions with occulted images during the solar eclipses. Our analysis yields a polar coronal hole temperature of about 1.0MK and an emis…
