Cusp-shaped Arcade in AIA and XRT
|
After a quiescent filament eruption occurred on 2010 Decemeber 6, a beautiful cusp-shaped post-event arcade was observed at 94 A by SDO/AIA around 01:00 UT on December 7 (see panel a). The cusp feature is considered evidence for on-going magnetic reconnection. Panels b-d show EUV images at 94 and 335 A by AIA and X-ray image by XRT at 06:00 UT on December 7. The cusp-shaped structure is barely visible in the 94 A image (panel b), and is visible in the 335 A (panel c). This cusp feature, especially the outer part of the cusp, is much better observed by XRT (panel d). Keywords: Cusp, Filament Filters: Ti_poly, AIA/94, AIA/335 |
