Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2022-03-07T00:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2022-03-07T00:12:00-CME-001 (version 2)
Source Location: N17W28
Active Region Number: 12958
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
PEA: Post eruption arcade
OFL: Moving/Opening field lines
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
Note: This CME is first seen as a faint partial halo to the NW in SOHO LASCO C2 (later in C3) and followed by a more bright and slightly more narrow shape to the W/NW in STEREO A COR2. The source of this CME is an eruption to the E/SE of AR12958 (N17W28) stretching across multiple longitudes from ~W20 to ~W45 based off of the dimming signature seen in SDO/AIA 193. The eruption is best seen in the SDO/AIA 193, 211, 94, 335, and STEREO A EUVI 195 wavelengths. From STEREO A's point of view, the eruption appears as opening field lines along the Eastern limb, while in SDO/AIA's point of view, the eruption is more clear with dimming, a post-eruptive arcade, and a brief EUV wave (seen best in SDO/AIA 211).
