RHESSI Observes the Flare over AR9906 - Time Tagged

Visualizations by Tom Bridgman Released on June 5, 2002
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.

Data Used:
RHESSI/X-ray Imaging Spectrometer
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
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.
