Note: This CME is visible to the south in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is likely an eruption on or near the western limb (~S30) starting around 2024-03-15T05:50Z seen in SDO AIA 131, 171, 193, 304 imagery which appears to experience a southern deflection due to previous eruptions and activity from Active Region 13599. Another possible but less likely source is field line movement seen over the SW limb starting around 2024-03-15T05:20Z seen in SDO AIA 171 and 193 imagery near S50. This event partially overlaps with CME: 2024-03-15T04:10Z.

Updated measurement based on the source location and best fit between SOHO LASCO C2/C3 and STEREO A COR2 imagery. As the source appears close to the limb, it is difficult to observe the precise source longitude and the measured longitude may vary slightly as a result. Multiple measurements were made using a range of parameters. However, after further analysis of the source eruption, this measurement was deemed the most accurate. |

This plane-of-sky measurement uses a longitude of 90 degrees as the source appears on or near the western limb. Multiple measurements were made based on possible source locations which resulted in longitudes ranging from 17 to 93 degrees. After further analysis it is more likely that the source location is near the western limb, and a confident measurement was made based on the best fit between SOHO LASCO C3 and STEREO A COR2 imagery using a longitude just beyond the limb at 93 degrees. |
