We present the first observation of a solar impulsive electron event spanning the entire solar wind-suprathermal particle energy range (few eV to hundreds of keV), obtained with the 3-D Plasma and Energetic Particle experiment on the WIND spacecraft. The electron energy spectrum fits to a power-law ~E-3 from ~40 keV down to a peak at ≲1 keV, with significant flux detected down to ~0.5 keV. Since the range of such low energy electrons in ionized hydrogen is much less than the column density of the corona, they must be accelerated high, ~1 R⊙ (solar radius) above the photosphere, for typical active coronal density models. ¿ American Geophysical Union 1996 |
