Description
We study intermittency of turbulence in the young so- lar wind at 0.17 au with NASA/Parker Solar Probe during the first perihelion. We observe localised en- hancements in power density that form correspond- ing peaks in Local Intermittency Measure (LIM) go- ing from MHD to kinetic scales. This indicates the presence of coherent structures in the observed signal. We observe a variety of coherent events from MHD to kinetic scales. We estimate the filling factor of the structures as well as their local topology.
