Heliospheric Current Sheet
WELCOME
The Solar and Heliospheric Research Group seeks a greater understanding of the diverse plasma processes at work within the solar system and throughout the universe. Research topics range from the physics of the solar interior and atmosphere to the solar wind, energetic particle transport, and acceleration processes.

SOLAR PHYSICS SUMMER SCHOOL

This summer school offers an intensive one-week course in topics related to the physics of the Sun. The course is designed for graduate and advanced undergraduate students with an interest in solar physics and who may possibly want to pursue a career in solar physics, space physics,or related field. The purpose is to provide an introduction to solar physics for students that do not have an opportunity to take such a course at their home institution. Website
