Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-19T23:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-03-19T23:48:00-CME-001 (version 1)
Source Location: S07W100
Note Keyword:
3P: 3-part structure CME
COL: Possible collision with previous CME
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
F: Flux Rope
Note: Faint loop CME visible to the northwest in SOHO LASCO C2/C3, with a faint flux rope feature more visible in STEREO A COR2 imagery. The source is the ejection of material from just beyond the southwest limb, first distinctly seen as a distinct instance of opening field lines and ejecta starting around 2025-03-19T23:15Z in GOES SUVI 304 and 284 imagery. Post-eruptive brightening extends onto the disk spanning from about S10 to S15 and W80 to W90, as seen in SDO AIA 304 at 2025-03-19T23:40Z. Associated surrounding field line movement extends into the northern hemisphere on or beyond the western limb, and some northern deflection occurs as the material erupts.

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 |

Measurement using best fit between SOHO LASCO C3 running difference and STEREO A COR2 difference imagery, as well as the approximated location of source seen in available UV imagery of the Earth-facing disk. The quality and cadence of STEREO A COR2 imagery was affected during time of analysis due to a campaign scheduled to last from 2025-03-18 to 2025-03-24. |
