Connections: Terrestrial Gamma Flashes and Lightning?
The RHESSI instrument not only views the Sun but can detect gamma-rays from sources on Earth as well.
Movie of TGFs detected by RHESSI over a 4 month period.
Lightning probability (January 1998 - February 2003) measured by TRMM-LIS. Brighter red is higher lightning probability.
TGFs have some correlation with lightning events?
Four months of TGFs as seen by RHESSI.

[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.
