Solar Magnetic Fields: from the photosphere through the chromosphere and into the corona

Coordinated study for Second Whole Sun Month Campaign

V. Andretta, S. Gibson, T. Hoeksema, T. Metcalf, H. Jones, K. D. Leka

Scientific Goals:

An understanding of the role currents play in the corona is essential to modeling the coronal magnetic field. This JOP is designed to use magnetic field observations, both line of sight and vector where available, in the photosphere and chromosphere to test force-free & potential models. Moreover we plan to compare magnetic field structures determined from modeled extrapolations to coronal structures. Specifically, we will

This analysis will be applied to

1) structures above active regions

2) coronal hole boundary expansion
