Observations of fast magnetosonic shocks from the solar wind to the inner heliosphere

This talk will review some current and planned observations of fast magnetosonic shocks from the corona, through the inner heliosphere, and into interplanetary space in the solar wind, and the application of these observations to the understanding of shock formation, particle acceleration, and space weather. The first half of the talk will focus on an online database of interplanetary shocks observed by spacecraft including Wind, ACE, and DSCOVR from the first Lagrange point near Earth and the value of statistical studies of shocks. Examples will be provided on the use of these observations to understand dissipation, particle acceleration, and the generation of intense radio emission by shocks. The second half will cover three examples of future observations of shocks closer to the Sun which will provide essential new knowledge of the shocks in the inner heliosphere. Solar Probe Plus and Solar Orbiter, which are just two years from launch, will be discussed in the context of shock observations. The proposed Sun Radio Interferometer Space Experiment (SunRISE), a low frequency imaging radio array in space that would provide the first images of radio emission and acceleration by fast shocks in the outer corona will also be presented.
