Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-19T08:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-19T08:48:00-CME-001 (version 1)
Source Location: S03W35
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
DIM: Dimming
Morphology Keyword:
Note: This CME is visible to the west in SOHO LASCO C2/C3 and GOES CCOR-1. In STEREO A COR2 imagery, however, this event is visible as a halo directed to the southeast. The source is likely a large dimming region centered near S03W35 starting around 2026-07-19T05:00Z seen in SDO AIA 193 and GOES SUVI 195/284 imagery. Western deflection is likely due to a large coronal hole east of the eruption site.
