| Outline of Final Research Achievements |
We performed several researches of solar magnetohydrodynamic activities associated with the coronal heating problem using available instruments such as the solar observing satellites "Hinode", "IRIS", and "SDO" and the ALMA telescope. Our main results are as follows. (1) We investigated peculiar motions of solar prominences observed in the off-limb region and found that they are caused by rotation related to magnetic reconnection between the magnetic fields of prominences and ambient coronal fields. (2) We discovered the strongest magnetic field of sunspots ever observed on the Sun and suggested a new hypothesis to generate the strong field by photospheric motions.
