DONKI: View SW Activity
Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-03-17T10:30Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2023-03-17T10:30:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
LS: Loop and Shock Candidate
Note: This CME overlaps the CME first seen in SOHO LASCO C2 at 2023-03-17T10:58Z to the SW. There are currently ongoing campaigns impacting the amount of available imagery for the SOHO LASCO C3 and STEREO A COR2 coronagraphs. The potential source of this CME is seen as moving/opening field lines along the SW limb in SDO/AIA 171 and GOES SUVI 284 starting around 2023-03-17T08:22Z.

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 |

There's a higher degree of uncertainty with these parameters due to the limited available imagery in the STEREO A and SOHO LASCO C3 coronagraphs. The longitude may vary by +/- 20 degrees depending on the fit. There could also be a wider shock portion that was not included in this measurement due to faintness and limited imagery. |
