On the Temporal Relationship between Coronal Mass Ejections and Flares
The temporal relationship between coronal mass ejections (CMEs) and associated solar Ñares is of great importance to understanding the origin of CMEs, but it has been difficult to study owing to the nature of CME detection. In this paper, we investigate this issue using the Large Angle and Spectrometric Coronagraph and the EUV Imaging Telescope observations combined with GOES soft X-ray observa...
متن کاملOn the Relationship Between Coronal Mass Ejections and Magnetic Clouds
We compare the substructures of the 1997 February 07 coronal mass ejection (CME) observed near the Sun with a corresponding event in the interplanetary medium to determine the origin of magnetic clouds (MCs). We find that the eruptive prominence core of the CME observed near the Sun may not directly become a magnetic cloud as suggested by some authors and that it might instead become the ”press...
متن کاملSolar Mini-Dimming Kinematics and Their Positive Correlations with Coronal Mass Ejections and Prominence
Solar mini-dimmings can be detect in the Extreme Ultra-Violet coronal eruptions. Here, sequences of 171_A images taken by Solar Dynamic Observatory/Atmospheric Imaging Assembaly on 13 June 2010 are used. In this special day, both of coronal mass ejection and prominence were observed. The average velocities and accelerations of 500 mini-dimmings which were detected using on feature based classif...
متن کاملSpatial Relationship between Solar Flares and Coronal Mass Ejections
We report on the spatial relationship between solar flares and coronal mass ejections (CMEs) observed during 1996-2005 inclusive. We identified 496 flare-CME pairs considering limb flares (distance from central meridian ≥ 45◦) with soft X-ray flare size ≥ C3 level. The CMEs were detected by the Large Angle and Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory (SO...
متن کاملCoronal Mass Ejections
A coronal mass ejection (CME) is an eruption of billions of tonnes of magnetically charged plasma from a star’s corona. The material ejected is sent into interplanetary space where it eventually dissipates. Should the material collide with a planet then that planet’s electro-magnetic field would be temporarily disrupted. If the Earth’s electro-magnetic field were disrupted by a large CME then p...
