First Flare movie for the RHESSI Instrument (Speed 105x Normal)

Visualizations by Tom Bridgman Released on March 20, 2002
An animation of an M-class flare viewed by the RHESSI instrument on February 20, 2002. On tape, this version plays at the maximum speed of one frame corresponding to 3.5 seconds of data collection time. The flare was located at -17.8 degrees South, 9.8 degrees West (heliographic coordinates) in NOAA active region number 9830.

Data Used:
RHESSI/X-ray Imaging Spectrometer
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.
