Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-01-27T16:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-01-27T16:00:00-CME-001 (version 1)
Source Location: S19W57
Active Region Number: 13972
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
U: Unknown
Note: CME first seen in SOHO LASCO C2 beginning at 2025-01-27T16:00Z, as well as by SOHO LASCO C3 in later frames. This event is not visible in STEREO A COR2 due to a data gap beginning at 2025-01-27T15:38Z. The source of this CME is field line movement and dimming seen near AR 3972 (S19W57) in SDO AIA 171 and 193 beginning at 2025-01-27T14:54Z. The dimming expands to the South of the Active Region suggesting a Southern deflection.

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

CME Analysis M2M_CATALOG LE true SWPC_CAT 56.0 -36.0 399.0 S 17.0 2025-01-28T00:29Z Measurement based on approximate source location and best fit in SOHO LASCO C2/C3. Due to the bizarre shape of this CME, especially in SOHO LASCO C2, this measurement was based on the furthest edge seen in SOHO LASCO C2 and more defined shape seen in SOHO LASCO C3 1: Result 1 (2.0 AU)
