summary
Summary
  • The high speed responses measured in LASCO C2 and STEREO COR2 coronagraph images show an association with Hinode and SDO/AIA jets.
  • Jet responses measured in C2/COR2 can also be observed in the Solar Mass Ejection Imager (SMEI) and Interplanetary Scintillation (IPS) analysis.
  • We can determine the mass contained in a jet, the volume of a jet, and its speed by tracing its density in the 3D SMEI analysis.
  • Observations of the same high speed response (at 2011 June 17 02:50 UT by the SDO/AIA ) in both LASCO C2 and COR 2 observations 90° in longitude from each other are a good indication that these measurements are material flow.
  • The jets contribute ~5% mass of solar wind estimated by observations from Ulysses.
