ABSTRACT
The Sun turns out to be a bright gamma-ray source due to cosmic rays interacting with the solar atmosphere. The gamma-ray flux is high and displays a variety of signatures such as time dependence in flux and surface morphologies. These suggests that solar magnetic fields significantly affect the cosmic-ray propagation near the surface of the Sun, and thus the gamma-ray production. Unfortunately, due to the complexity of solar magnetic fields, it is not completely understood what and how solar magnetic fields are responsible for the solar observations. In this talk I will review the current observations, discuss possible ideas in try to understand the data, hopefully can convince you that gamma rays could be a useful probe of the Sun in the near future.
