Close-up view of the solar active region AR9906 on April 21, 2002 with TRACE and RHESSI data. RHESSI observes x-rays from this flare. The red contours represent the 12-25 keV photon energy range and the blue contours represent 50-100 keV.

Datasets used

  • [RHESSI: X-ray Imaging Spectrometer]

    ID: 101
    Sensor: X-ray Imaging Spectrometer Dates used: 2002/04/21T00:36:49UT-2002/04/21T02:04:42UT

    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]

    ID: 106
    Dates used: 2002/04/21T00:36:49UT-2002/04/21T02:04:42UT

    The TRACE satellite views the Sun at ultraviolet wavelengths with high temporal (approximately 1-12 seconds) and spatial (1 arcsecond per pixel) resolution. Launched on April 2, 1998, it orbits the Earth in a Sun-synchronous orbit.
