COMPTEL Image Sequence of Long-duration Solar-flare emission
One of the major discoveries of the Compton Observatory is a new
class of solar flare with long-duration, high-energy gamma-ray emission.
This image shows the decay of 0.8 to 8 MeV gamma radiation
from nuclear line emission,
recorded by COMPTEL for the solar flare of 15 June 1991.
During the onset of this flare
the CGRO was on the dark, "night" side of the Earth, and
it was not until 40 minutes after the impulsive
phase of this event that COMPTEL was able to collect its first data.
Yet, this sequence of images demonstrates that MeV gamma radiation
persisted for over an hour after the onset of the flare,
implying that energetic particles continued to interact at the
flare site long after the impulsive phase had passed.
image of the Sun obtained in solar neutrons
has also been produced
from COMPTEL data recorded for the flare of 15 June 1991.
