Signatures of interchange reconnection: STEREO, ACE and Hinode observations combined
Sauvaud, J. -A.; Luhmann, J. G.; van Driel-Gesztelyi, L. +8 more
Combining STEREO, ACE and Hinode observations has presented an opportunity to follow a filament eruption and coronal mass ejection (CME) on 17 October 2007 from an active region (AR) inside a coronal hole (CH) into the heliosphere. This particular combination of "open" and closed magnetic topologies provides an ideal scenario for interchange recon…
Multispacecraft observations of a prominence eruption
Andretta, V.; Del Zanna, G.; Bemporad, A. +2 more
On 9 May 2007 a prominence eruption occurred at the West limb. Remarkably, the event was observed by the STEREO/EUVI telescopes and by the HINODE/EIS and SOHO/UVCS spectrometers. We present results from all these instruments. High-cadence (~37 s) data from STEREO/EUVI A and B in the He II λ304 line were used to study the 3-D shape and expansion of…
