Activity ID: 2023-05-07T23:12:00-CME-001 (version 1)
Source Location: N17W07
Active Region Number: 13296
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: This CME is visible as a partial halo to the NW in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is likely an eruption and subsequent long duration M1.6 flare from AR 3296 starting around 2023-05-07T22:15Z in SDO AIA 131, 171, 193, 304 imagery. An opening of field lines is visible at the time of the eruption with post eruptive dimming and arcades visible starting around 23:45Z in SDO AIA 193 and STEREO A EUVI 195 imagery.

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 |

Preliminary measurement following the bulk of the CME. There are only 3 images available in STEREO A COR2 due to a data gap, so this measurement relies heavily on SOHO LASCO C3. |

This measurement tracks the brighter, inner bulk portion as measured by Carina Alden. The bulk appears to move much slower than the wider, surround shock portion. It is difficult to measure the bulk and shock separately due to the mostly irregular shape of this CME. |
