Solar flares catalog

The RELEC experiment was realized onboard a small (MKA-FKI PN2) spacecraft named "Vernov" in honor of Academician Sergei Nikolaevich Vernov, the founder of Russian space physical science. The spacecraft is based on the "Karat" platform designed and manufactured by the S.A. Lavochkin Research and Production Association.

The RELEC experiment onboard the Vernov satellite was realized under the patronage of the Russian Federation Space Program with funding by the Russian Space Agency. The Vernov spacecraft was launched on July 8, 2014 to the solarsynchronous orbit with the following parameters: apogee of 830 km, perigee of 640 km, inclination of 98.4 degrees , and period of 100 min. The RELEC set of scientific instruments was operated onboard Vernov till December, 10, 2014. The main operational mode was observational with all instruments operating simultaneously, and the nominal data transfer to the Earth was about 1.2 GB/day. The goals of RELEC mission were study of Terrestrial Gamma-ray Flashes (TGFs) and study of relativistic electrons of Earth’s radiation belt precipitation with its possible connection with atmospheric Transient Luminous Events (TLE), as well as study of the solar X- and gamma-emission and Gamma-Ray Bursts (GRB). Also RELEC permitted monitoring the radiation and electromagnetic environment in the near-Earth Space. Measurements of X- and gamma-ray emission from solar flares were carried out with DRGE instrument.
