The quasi-periodic behavior of recurrent jets caused by emerging magnetic flux

Yang, J. Y.; Liang, H. F.; Jiang, Y. C. +2 more

A series of recurring jets occurred at the edge of an active region NOAA 11459 on 2012 April 20, and they were observed simultaneously at EUV and soft X-ray wavelengths. They also were sometimes associated with a hard X-ray source at the base region. The jets might have resulted from magnetic reconnection between the newly emerging flux and the pr…

Improved SOT (Hinode mission) high resolution solar imaging observations

Koutchmy, S.; Adjabshirizadeh, A.; Goodarzi, H.

We consider the best today available observations of the Sun free of turbulent Earth atmospheric effects, taken with the Solar Optical Telescope (SOT) onboard the Hinode spacecraft. Both the instrumental smearing and the observed stray light are analyzed in order to improve the resolution. The Point Spread Function (PSF) corresponding to the blue …
