"Future Problems in Photospheric Fields and Flows"
Brian T. Welsch, Space Sciences Laboratory, University of California, Berkeley
I was recently invited to speak at the Hinode-7 conference about new analyses of photospheric fields and flows in a session on Future Problems & Observations. Magnetic evolution observed in high-cadence sequences of high-resolution, seeing-free magnetograms of the photosphere by Hinode (and of the chromosphere by the planned Solar-C) can constrain the dynamics of near-surface magnetic and velocity fields. Such observations can address open questions about several key topics in solar physics, including coronal heating, flux emergence and submergence, and impulsive magnetic dynamics in flares. I will discuss questions in these areas posed by recent research results, and propose ideas to address these questions with future observations.
