Summary[edit | edit source]

Description

The sun as seen in gamma rays by COMPTEL during a June 15, 1991, solar flare. The sun is ordinarily not known to produce gamma rays, but during this solar flare, steams of neutrons poured into the intrastellar medium to create gamma rays. This image provided the first evidence that the sun can accelerate particles for several hours. This phenomenon was not observed before CGRO and represents a new understanding of solar flares.
