1. 1 Hinode Coordinated Observations: Coronal Cavities On February 23, 2012, a coronal cavity and associated prominence was observed by Hinode. XRT data clearly shows a bright center in the cavity. Temperature analysis from XRT shows that the bright center is hot (~2 MK), and the cavity is less dense than its surroundings. bright center P.

2. 2 Hinode Coordinated Observations: Coronal Cavities EIS scanned the region of the cavity, showing a partial ring of red-shifted emission. The contours of the red-shifted emission are shown on an EIS raster and an XRT image – the red-shifted plasma surrounds the bright core viewed by XRT. P.

3. 3 Hinode Coordinated Observations: Coronal Cavities SOT images of the associated prominence in Hα red wing and blue wing give information about the prominence motion Data from the three Hinode instruments are complementary, and explore the structure’s dynamics, morphology and thermodynamics. Goal is to understand the structure of the flux rope which is the source of the hot center cavity P.
