TITLE=Solar Physics From Unconventional Viewpoints JOURNAL=Frontiers in Astronomy and Space Sciences VOLUME=5 YEAR=2018 URL=https://www.frontiersin.org/journals/astronomy-and-space-sciences/articles/10.3389/fspas.2018.00032 DOI=10.3389/fspas.2018.00032 ISSN=2296-987X ABSTRACT=

We explore new opportunities for solar physics that could be realized by future missions providing sustained observations from vantage points away from the Sun-Earth line. These include observations from the far side of the Sun, at high latitudes including over the solar poles, or from near-quadrature angles relative to the Earth (e.g., the Sun-Earth L4 and L5 Lagrangian points). Such observations fill known holes in our scientific understanding of the three-dimensional, time-evolving Sun and heliosphere, and have the potential to open new frontiers through discoveries enabled by novel viewpoints.
