RHESSI and TRACE View of January 20, 2005 Solar Flare

  • Released Tuesday, May 24, 2005
View full credits

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.

As the TRACE imager saturates, we see multiple hot-spots at the loop footpoints in RHESSI.

Closeup of AR 10720.  Blue high-energy emission marks the footpoints of the coronal loops.  The lower-energy red emission is from the
loop structure.  See note below under ImageMods.

Datasets used

  • [RHESSI: X-ray Imaging Spectrometer]

    ID: 101
    Sensor: X-ray Imaging Spectrometer Dates used: 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.
