Solar flares. The plot on this page shows us the most recent 24-hour solar X-ray data from the primary GOES satellite. You can zoom in on this plot by selecting a time period that you wish to view and even export the graph as a JPG, PDF, SVG or PNG file.
Real-time auroral and solar activity. 17:20:51 UTC.
Last 24 hours: An isolated M flare brought the period’s solar activity to a moderate level. Flare productivity increased compared to the previous period’s eight flares. During the current...
Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts. This flare is classified as an X2.3 class flare. X-class denotes the most intense flares, while the number provides more information about its strength.
NASA’s Solar Dynamics Observatory captured this imagery of an X1.7 solar flare peaking at 10:09 p.m. EDT on May 13, 2024. The clip covers 9:00 to 11:48 p.m. and shows 171 angstrom light, a subset of extreme ultraviolet light that highlights hot loops of plasma in the Sun's corona.
The daily Solar and Geophysical Activity Summary is a brief list of solar and geophysical events and indices for the previous UTC day, including energetic solar flares, proton events, geomagnetic activity, and stratospheric warming alerts.
NASA’s Solar Dynamics Observatory captured nine X-class solar flares between May 10-16, 2024. This video shows the Sun in extreme ultraviolet wavelengths (131 Ångstroms) colorized in teal. This wavelength of light highlights the extremely hot material in flares.
