The Astrophysical Journal, 599:1418–1425, 2003 December 20 TETHER-CUTTING ENERGETICS OF A SOLAR QUIET-REGION PROMINENCE ERUPTION Alphonse C. Sterling1, 2 and Ronald L. Moore NASA Marshall Space Flight Center, SD50/Space Science Department, Huntsville,AL 35812; [email protected], [email protected] Received 2003 May 31; accepted 2003 August 19 太陽雑誌会 2004/2/2 殿岡 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 ● Instrumentation and data Observations: EIT 284A Observations: SXT Observations: Figure3 Observations:Figure4 Light curves and trajectory of the prominence. Upper: EIT, Lower: SXT Energetics estimating the amount of energy required for the prominence eruption, the gravitational energy dominates the kinetic energy by 2 orders of magnitude.
