Current Solar Images
WARNING: When observing the Sun, be sure to do so safely! Use only equipment that is designed specifically for that purpose and is produced by reputable manufacturers. Follow their directions closely. Do not improvise your own filter material for solar observing. If you are careless, you risk instant and permanent vision loss or injury.
The following is an aggregation of various online resources that show current solar conditions.
Global Oscillation Network Group (GONG)
The Global Oscillation Network Group (GONG) studies changes in the Sun’s internal structure by means of helioseismology.
GONG posts up-to-the-minute H-alpha images of the Sun’s chromosphere. These images are a close representation of what one would see in the eyepiece of a telescope equipped with an H-alpha filter. For more information, see the GONG H-alpha information page and NSO information page.
High-quality images dating back to 2010 are available via HTTP and FTP.
Magnetogram images and Potential-field Source-surface (PFSS) models (see this information page for more) are also available.
Solar Dynamics Observatory (SDO)
The following is a selection of SDO images pulled from the SDO Data page. They represent views of the Sun’s photosphere, chromosphere, transition region, and corona. Refer to this article on how SDO sees the Sun and these descriptions of SDO imaging in various wavelengths for more information. These images are provided as a courtesy of NASA/SDO and the AIA, EVE, and HMI science teams.
