| == Description == :: First C2 Appearance - Taken from the SOHO/LASCO CME Catalog :: Location (Apparent Loc) - Latitude and longitude of CME source region in the heliographic coordinate. The latitude and longitude in parentheses indicates the source region location without solar b angle correction. :: DSC - Projected distance on the plane-of-sky from the solar center to CME source region. :: SPA - Position angle of CME apparent location. :: CPA - Central position angle. :: MPA - Measurement position angle. :: Width - Angular width. :: Speed - Linear speed. :: Acc - Acceleration. :: Def - Deflection. E: Equator-ward, P: Pole-ward, R: Radial event. :: EIT Ref-Time - A time when the EIT image shows CME initiation clearly. :: CL - The confidence level of the identification. :: The parameters in the columns 2, 6, 7, 8 and 9 are adopted from CDAW CME Catalog. == The LIST OF CME SOURCE LOCATIONS is generated == :: by the members of STEP Team at USTC: Yuming Wang, Caixia Chen, Bin Gui, Chenglong Shen and Pinzhong Ye :: based on the SOHO/LASCO CME CATALOG generated and maintained at the CDAW Data Center by NASA and The Catholic University of America in cooperation with the Naval Research Laboratory :: and the SOHO/EIT MVI movies generated by the Naval Research Laboratory. :: Comments or questions about this list could be addressed to Dr. Yuming Wang (ymwang@ustc.edu.cn), :: or written here. |
