High Energy Spectroscopic Imager (HESSI) - HESSI was recently selected for launch in mid-2000 as part of NASA's Small Explorer Program. HESSI's primary mission is to explore the basic physics of particle acceleration and explosive energy release in solar flares.

SOHO: The Solar and Heliospheric Observatory - Homepage of the spacecraft observatory SOHO, developed jointly by NASA and ESA (the European Space Agency). Extensive data from twelve separate instruments designed to study the internal structure of the sun, its extensive outer atmosphere, and the origin of the solar wind.

Large Angle and Spectrometric Coronagraph Experiment (LASCO) - The LASCO, one of eleven instruments included on the SOHO spacecraft, is a coronagraphic telescope designed to block light from the solar disk in order to see the faint emission of the corona.

Global Oscillation Network Group (GONG) - The GONG Project is a community-based solar observation network of six telescopes located at strategic points around the earth. GONG is conducting detailed studies of the solar internal structure and dynamics.

The Wilcox Solar Observatory - New low-resolution maps of the sun's magnetic field are posted each day, as are observations of solar surface motions.

UC/Lick Observatory - Homepage of the University of California's Lick Observatory in Santa Cruz, California.
