The SOHO project, SOlar and Heliospheric Observatory (SOHO) is a joint project of international cooperation between the European Space Agency (ESA) and NASA, and has studied several aspects of the Sun and heliosphere.
The National Research Council has released A Decadal Strategy for Solar and Space Physics (Heliophysics). A video of the public release of the report is also available.
The website formerly known as the Active Region Monitor, offers all up-to-date information on solar activity, including images, solar flare locations, and solar flare predictions.
The LMSAL events page gives a graphic view of solar and heliospheric activity through soft X-ray, energetic proton, and solar wind data.
Within NASA, research in solar physics falls within the discipline of Heliophysics, the study of the Sun, the heliosphere, and the plasma and magnetic field environment of the planets. Information on the big questions in the field, the focus areas in the field, and the missions that monitor conditions throughout the heliosphere and enable research in the field is available at the NASA Science Website.
