RHESSI Observes the Flare over AR9906 - zoom with times
Zoom in 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.
Movie of RHESSI and TRACE data.

Initial appearance of emission in 12-25 keV.

Upflow viewed in TRACE appears at the center of the RHESSI emission.

RHESSI emission expands to an arc, apparently around the limb of the Sun.

TRACE emission brightens in RHESSI 12-25keV contours and new RHESSI emission at 50-100keV appears on the solar surface.

Last gasps of x-ray emission from this flare.

-
[RHESSI: X-ray Imaging Spectrometer]
ID: 101The 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.
