High resolution solar physics from rockets
Abstract
Explosive events are highly energetic phenomena that are frequently seen throughout the quiet and active sun, particularly in spectral lines formed at transition zone temperatures. Sufficient observational evidence has now been developed to conclusively demonstrate that some explosive events are caused by magnetic reconnection in emerging magnetic flux regions. It is also consistent with observations of photospheric magnetic flux cancellation to propose that all explosive events are the result of magnetic reconnection. By combining the observational facts concerning photospheric flux cancellation and transition zone explosive events it can be shown that reconnection in the quiet solar atmosphere proceeds in bursts at sites much smaller than the boundary between opposite polarity flux elements that are observed to cancel in magnetograph sequences.
