Large-Scale Heliospheric Structure during Solar-Minimum Conditions using a 3D Time-Dependent Reconstruction Solar-Wind Model and STELab IPS Observations

Interplanetary scintillation (IPS) observations provide information about a large portion of the inner heliosphere. We have used Solar‐Terrestrial Environment Laboratory (STELab) IPS velocity and g‐level observations with our three‐dimensional (3D) reconstruction model to determine velocities and densities of the inner heliosphere in three dimensions. We present these observations using synoptic maps generated from our time‐dependent model that can measure changes with durations of less than one day. These synopses show large‐scale stable solar‐wind structure during solar‐minimum conditions in relation to transients that are present during this period. These are also available as differences relative to the background. Here, we concentrate primarily on data covering the 2007–2009 International Heliophysical Year (IHY).
