AGU meeting 2019 presented many interesting observation from Parker Solar Probe (PSP).
These observation are quite relavent for the CME propogation and solar wind studies.

- Switchbacks are present at the timescale of 25 mins in the spacecraft frame.
- The switchbacks occurs from the interaction of fast and slow moving streams of plasma.
- There is turbulence at the interface.
- He-III is an indicator of the seed population from the active regions.
- Power laws of the energy distribution in co-rotating interaction region (CIR) shows variety of power-laws. Occurance rates of low and high energy steams have -1 to -2.6 and -5 to -7 slopes respectively.
- Stream Interaction Regions (SIR) and Solar Energetic Proton (SEP) results
