Description
ICME Event list of the ICME signature in-situ at ACE compared with CME at LASCO C2 or STEREO COR2.
A comprehensive event list of chain of cause-effect of solar eruptive events from Sun to Earth. In this study, the tracking is carried out backward from the Earth to the Sun, starting from ICMEs observed at in-situ.

Parameter #9
Name
SEEDS VEL C2
Description
The velocity of the CME, as determined by the SEEDS C2 Catalog. These velocities are for quick reference only, and should not be taken at face value. There are different errors that are present in these velocities and they should not be used for an serious study or research work
Support
Parameter #10
Name
SEEDS VEL A
Description
The velocity of the CME, as determined by the SEEDS STEREO Catalog. These velocities are for quick reference only, and should not be taken at face value. There are different errors that are present in these velocities and they should not be used for an serious study or research work
Support
Parameter #11
Name
SEEDS VEL B
Description
The velocity of the CME, as determined by the SEEDS STEREO Catalog. These velocities are for quick reference only, and should not be taken at face value. There are different errors that are present in these velocities and they should not be used for an serious study or research work
Support
Parameter #12
Name
AVG. VEL
Description
The average velocity of the CME as calculated by determining the time of the CME in C2 and the beginning of the signature in-situ
Support
Parameter #13
Name
Velocity
Description
The average velocity of the ejecta at ACE
Support
Parameter #14
Name
Transit time
Support
Parameter #15
Name
DST PEAK
Description
The lowest value of the DST index
Support
Parameter #16
Name
DST PEAK TIME
Description
The time when the lowest value of the DST index occurs (as long as the peak is below -40)
Support
Parameter #17
Name
EJECTA START TIME
Description
The beginning of the CME Ejecta in-situ (if there is no shock this is the same as the ICME start time)
Support
Parameter #18
Name
