Abstract:
SECCHI-COR1 is an internal occulted coronagraph on the spatial mission STEREO which was lunched in october 2006. It observes the solar corona in white-light emission mostly due to Thomson scattering radiation. During the period of 2007 and 2008 years jet-like structures were observed almost daily in these images. They are supposed to be signatures of slow solar wind whose source regions are not yet known. Sometimes they can be identified on the disk with bright points observed in ultraviolet images by EIT instrument on SOHO or EUVI instrument on STEREO. In this study we analize the dynamics of these jets as well as their position in a 3D coordinate system. We also discuss their association with the bright points and possible mechanisms of emission.
