The source was distinguished by its departure from the Neupert Effect -
hard X-rays peaked late, and were much brighter than expected.
The hard X-ray source matched the position of a
compact microwave source judged to be free-free emission.
The source exhibited an outward motion unprecedented
for a hard X-ray source, and one which matched the motion of the unusual
microwave source.
The moving structures were embedded within a CME and (arguably) were
associated with erupting filament material.
The moving hard X-ray/microwave source coincided with
a slow-drift decimetric source that preceded the associated Type II (?)
burst.
