Coronal Mass Ejection

Source Location: S19W40
Active Region Number: 13262

Morphology Keyword:
Note: Minor, faint, but wide eruption first seen in SOHO LASCO C2 at 2023-03-30T21:12Z in the southwest, visible in both the SOHO and STEREO A coronagraphs. The source appears to be associated with a minor eruption from AR3262 located near S19W40 and dimming seen best in SDO 193, though the CME's leading edge quickly disappears before exiting the field of view, and the CME itself is too diffuse to reliably pair images between SOHO and STEREO A well. As such, there is significant uncertainty in the width and velocity parameters associated with the measurements.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |

Speculative leading edge measurement using SOHO and STEREO A imagery but with very high uncertainty in width and velocity since the leading edge is extremely diffuse and difficult to track. The measurements uses a feature due south in an attempt to track the leading edge out towards the field of view. |

Measurement which is based on the best fit between SOHO LASCO C2 and STEREO A COR2 which considers a more eastward longitude (i.e. greater deflection) relative to the source location. |
