Abstract:
In anticipation of the PUNCH mission, we examine deep exposure data from the special campaign of the STEREO SECCHI COR2 instrument. Data collected over April 14-16, 2014, representing altitudes of 4-15 solar radii, show clear flow structures throughout the field of view. We examine the variations in the derived flow as a function of altitude and polar angle, to present a picture of the solar wind velocities and acceleration through the corona and inner heliosphere.
