Living Catalog of Stream Interaction Regions

Stream Interactions Regions (SIRs) are long lived large scale structures in the solar wind that are able to accelerate ions to high energies. While there have been many observations of these structures at 1 au (the distance the Earth is from the Sun), there are very few observation closer to the Sun. With the launch of Parker Solar Probe we are now able to study SIRs as they evolve while flowing away from the Sun allowing us to investigate how the aspects such as pressure and density pile-ups occur and how this may affect ion acceleration. To help enable these investigations, we have created a living catalog of SIRs that will be updated regularly along with corresponding observations at 1 au. Our method has been published in Astronomy & Astrophysics and the living catalog will be housed here!
