Introduction
Two different types of filament and prominence eruptions ..
active region and quiet region eruptions
●“both types of eruptions are aspects of a more general
magnetic eruption process and that the mechanism driving these
eruptions is the same in the two cases”
●Quiet-region prominence eruption of 1999 Feb 8-9
●the expected observational detectability of tether-cutting
reconnection
●

Energetics
estimating the amount of energy required for the
prominence eruption,
the gravitational energy dominates the
kinetic energy by 2 orders of magnitude.
Energetics -2Estimating heating energy associated with tether cutting reconnection.
