Note: Partial halo CME seen to the south/southeast in SOHO LASCO C2/C3 and STEREO A COR2. Source is a filament eruption on the Earth-facing disk stretching from S15E00 to S15E35, with liftoff starting around 2024-01-20T08:27Z. Liftoff of material and post-eruptive brightening can be seen in SDO AIA 304 at 2024-01-20T08:27Z. Opening field lines seen in SDO AIA 171 and dimming seen in SDO AIA 193 starting at 2024-01-20T08:39Z - dimming spans from S20 up to N10; from E05 to E40. Posts-eruptive arcades seen in SDO AIA 171/193 and STEREO A EUVI 195 forming at 2024-01-20T09:13Z. This eruption can also be seen in STEREO A EUVI 304 imagery as brightening and ejecta, and in STEREO A EUVI 195 imagery as dimming and post-eruptive arcades. This CME overlaps with another filament eruption on the NE limb which resulted in CME:2024-01-20T09:36Z.

If there are multiple CME analysis entries for a single CME, earlier measurements are marked as false when new or more accurate measurements are made. This is a helpful flag if you would like to download only one most accurate CME analysis per CME |

Measurement of irregular leading edge. Measurement made using source location as seen in UV imagery and best fit between coronagraphs. This CME overlaps with a simultaneous CME seen to the northeast, making it a bit difficult to distinguish the northern portion of the leading edge in difference imagery. This adds some uncertainty to the measurement. |

Shock measurement using source location seen in UV imagery and best fit between coronagraphs. This shock front has a slightly asymmetrical shape. There is inherent uncertainty in this measurement due to the head-on directionality of the CME (i.e. being a partial halo). |
