RHESSI and TRACE View of January 20, 2005 Solar Flare

RHESSI spacecraft images of gamma-rays (blue) and X-rays (red) thrown off by the hottest part of the flare are shown with UV images from the TRACE spacecraft. The gamma rays are made by energetic protons at the Sun. Scientists were surprised that the gamma rays matched the energy spectrum of protons at Earth: the proton storm may have come directly from the Sun and not from the CME as anticipated.

Data Used:
RHESSI/X-ray Imaging Spectrometer
2005/01/20T06:20:13 - 2005/01/20T07:26:00
The RHESSI instrument is an imaging spectrometer observing the Sun at X-ray to gamma-rays (photon energies of 3 keV to 17 MeV) at time resolutions of a few seconds. (eV stands for "electron volt" and is a unit of energy. Note that photons of visible light have energies of 2-3 eV. 1 keV is a thousand electron volts and 1 MeV is a million electron volts.
TRACE/Optical Telescope/1600 Angstroms
2005/01/20T06:20:00 - 2005/01/20T08:43:57
Note: While we identify the data sets used in these visualizations, we do not store any further details nor the data sets themselves on our site.
