THE EXTENSION OF EXPLOSIVE EVENTS FROM THE TRANSITION REGION TO THE CORONA

We describe the properties of high velocity events in the corona and u pper transition region and propose that they are the same phenomenon a s the well studied explosive events seen in the lower transition regio n around T=10(5) K. Furthermore, we discuss how the SOHO spectrometers , CDS and SUMER, may be used to check this conjecture. Magnetic reconn ection has been considered a strong candidate for the physical mechani sm causing explosive events. We present a phenomenological model showi ng how some of the observed properties of explosive events may be expl ained by reconnection occurring in small magnetic loops.
