HAO Education Pages

A part of the mission of the High Altitude Observatory is to enhance and contribute to solar and solar-terrestrial physics education. The HAO education pages are designed for the use of both teachers and students. The material is arranged according to increasing skill level:

          sun Basic Facts, Q & A
          slides Slide Sets, Image Maps, Suggested Reading
          books Historical Material
          equation Lecture Notes, Tutorials
HAO offers appointments for undergraduate and graduate students, and also hosts both levels of students through the SOARS program. HAO scientific staff engage in various community outreach activities, development of curriculum material such as educational slide sets, and participate in project LEARN. HAO is a division of the National Center for Atmospheric Research, which has many additional opportunities for education and training. More information on current NCAR educational activities can be found in the 1999 Annual Scientific Report.
