RHESSI Observes the Flare over AR9906 - rotate view with times

Zoom in (with rotation) to solar active region AR9906 on April 21, 2002 with SOHO/EIT,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
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.
SOHO/Extreme-UV Imaging Telescope (EIT)/195 Filter also referred to as: SOHO/EIT 195
NASA and ESA - 2002/04/21T00:36:49UT-2002/04/21T02:04:42UT
TRACE/Optical Telescope/195 Angstroms
