Auroral Activity
".Instruments
on board the NOAA Polar-orbiting Operational
Environmental Satellite (POES) continually
monitor the power flux carried by the protons
and electrons that produce aurora in the
atmosphere."
".When displayed in geographic coordinates,
the statistical patterns of auroral particle
power input provide a "best-guess" estimate
of the locations, geographic extents, and
intensities of aurora at the time of the
satellite pass that provided the estimate
of auroral activity. Energetic auroral particles
(primarily electrons) not only produce the
visible aurora but also greatly influence
the properties of the ionosphere and are
connected."
