The weak field approximation is a conceptually simple and computationally light method for inferring the magnetic field strength and its orientation in the Sun’s atmosphere.

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.
Stan Solomon et al, dicuss a new modeling capability that self-consistently couples physics-based magnetospheric 18 electron precipitation with its impact on the ionosphere, representing a significant improvement over previous models.
Nicholas Pedatella notes that geomagnetic storms are an important driver of variability in Earth’s ionosphere, and can have significant societal impacts through the ionosphere’s impact on communications and navigation systems (e.g., GPS).
BC Low elaborates on the extraordinary sixty years of progress made to space observation of the Sun, solar wind, planets and their magnetospheres. He notes that space platforms complementing ground-based observatories have transformed solar physics.
