Top: GOES X-ray light curve. During the colored time range, the eruption was observed. Middle: Time-distance diagram along the eruption (the slit position is shown in the right panel). It was decelerated after 18:13UT. Bottom: Doppler gram for the eruption. Direction of the eruption along the line-of-sight was changed at 18:13UT. Summary & Conclusions We examined the 3D velocity field of the H  filament eruption and EUV flux rope associated with the flare. They are ejected in the 2-step energy releases, and finally they caused a CME. This work is a research outcome based on the 2 nd FMT-WS held at Hida Obs., Kyoto Univ. on July 2011.

Multi-wavelength observation of the filament eruption. In the top view (right column) taken by STEREO-A/EUVI we can confirm the change of the direction of eruption. Fig4. Top: Temporal evolution of the EUV (94A) flux rope observed by SDO/AIA. Middle: GOES X-ray light curve overlaid with RHESSI hard X-ray (50-100keV) light curve. During the colored time range, the H  eruption was observed. Bottom: Time-distance diagram along the eruption (the slit position is shown in the left panel). At the time the disappearance, EUV flux rope was decelerated. But, after the second hard X-ray burst, the flux rope was accelerated again. 日本天文学会 2012 年春季年会 (ASJ-Spring Meeting 2012) A71c ~88° Fig5.

The velocity of the CME is about 700km/s Abstract We present a detailed 3-dimensional features of the filament ejection and coronal mass ejections associated with the M4.4 flare that occurred on 2011 March 8 flare at the active region NOAA 11165. The H  full-disk images were successfully obtained by FMT 1 relocated from Hida Observatory of Kyoto University to Ica University in Peru under the international collaboration of the CHAIN 2 -project (see also Morita et al. (M18a) and UeNo et al. (A21a) in this JAS-Spring Meeting). Based on the FMT date we derived the 3-dimensional velocity field of the filament ejection. The features in extreme ultraviolet were also obtained by AIA 3 on board SDO 4 and EUVI 5 on board STEREO 6 -Ahead satellite. In this paper we report in detail the evolution of the ejection followed by a coronal mass ejection. 1 Flare Monitoring Telescope, 2 Continuous H-Alpha Imaging Network, 3 Atmospheric Imaging Assembly, 4 Solar Dynamic Observatory, 6 Extreme-Ultraviolet Imager, 6 Solar TErrestrial Relations Observatory 1 Time slice of H  center image GOES X-ray light curve 18:12:1918:15:00 H  Filament eruption start @18:10UT velocity change @18:13UT 30km/s 80km/s disappear @18:18UT 1 2 2 FMT-Peru Ha center SDO/AIA 171ASTEREO/EUVI 171A SDO/AIA 94A images 1 2 1 GOES+RHESSI 50-100keV 2 position of the STEREO-Ahead satellite Coronal Mass Ejection (CME) disappearance of H  filament SOHO/LASCO 700km/s flare flux rope
