Coronal Mass Ejection

Activity ID: 2023-01-11T17:00:00-CME-001 (version 4)

OFL: Moving/Opening field lines
Morphology Keyword:
Note: This is a large, bright and wide CME visible to the SE in SOHO LASCO C2/C3, and STEREO A COR2 imagery. The likely source is seen as clear moving/opening field lines beyond the SE limb in STEREO EUVI A 195 after 2023-01-11T16:35Z, followed by high rising post-eruptive arcades on the limb in EUVI A 195 an hour later. This CME was has been analyzed and deemed to likely be backsided. (Note: There also was an eruption in the SE on the Earth-facing disk seen in AIA 304 starting 2023-01-11T20:45Z (with a significant-area dimming south of the AR 3184(S13E41) seen in AIA 193) but this eruption was several hours later than the start of the CME and thus likely unrelated to it. No CME has been associated with the SE eruption).

Analysis made with more C3/COR2A imagery after the downlinks. Longitude is still not certain because the source was behind the E limb in STEREO A. |

This is a preliminary measurement based off of the best fit between the feature in SOHO LASCO C3 and STEREO A COR2 difference imagery. The CME appears to be more narrow in STEREO A COR2 imagery, but could be slightly wider in SOHO LASCO C3 imagery. Updated parameters may be added. |
