2. 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

3. Instrumentation and data

4. Observations: EIT 284A

5. Observations: SXT

6. Observations: Figure3

7. Observations:Figure4 Light curves and trajectory of the prominence. Upper: EIT, Lower: SXT

8. Energetics estimating the amount of energy required for the prominence eruption, the gravitational energy dominates the kinetic energy by 2 orders of magnitude.

9. Energetics -2- Estimating heating energy associated with tether cutting reconnection. (radiated energy) + (thermal energy) a heating rate of 10 5 –10 7 ergs cm 2 s 1,

10. Discussion ● Previous results.. quiet region and active region eruptions ● Dimmings ● The heating due to tether cutting reconnection ● Summaries regardign tether cutting reconnection ● The assumption of a constant energy ratio
