3459 20180129160302.0 POSTER-2018-0031 West, Matthew Further Exploration of Post-Flare Giant Arches 2017 2017-08-22 Recent observations from the SWAP EUV imager on-board PROBA2 and SXI X-ray observations from the GOES satellite have shown that post-flare giant arches and regular post-flare loops are one and the same thing. However, it is still not clear how certain loop systems are able to sustain prolonged growth to heights of approximately 400000 km (>0.5 solar-radii). In this presentation we further explore the energy deposition rate above post-flare loop systems through high-energy RHESSI observations. We also explore the difference between the loop systems through a multi- wavelength epoch analysis. 3ESA_PROBA2SOC/ 3ESA_PROBA2SOC/ 3ESA_PROBA2SOC NO Post-Flare Giant Arches Seaton, Daniel B Dennis, Brian R Feng, Li American Astronomical Society, SPD meeting #48, Portland, USA matthew.west@observatoire.be http://adsabs.harvard.edu/abs/2017SPD....48.0201W CPOSTER
