Note: CME first seen to the N in SOHO LASCO C2 starting at 2025-04-28T15:48Z. Also seen to the N in SOHO LASCO C3 and STEREO A COR2. This CME is best seen in running difference imagery and partially overlaps with earlier, slower CME: 2025-04-28T10:36Z. Later in propagation into SOHO LASCO C3, the CME appears to accelerate. This acceleration could be caused by an additional front that is sporadically visible for a few frames across SOHO LASCO C2/C3 but is not independently measurable. No additional coronal signatures were visible as possible sources for this CME; however, due to the far northern latitude (~N85), a very wide range of longitudes are possible. The source could be farsided.

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 |

Measurement based on triangulation between SOHO LASCO C2/C3 and STEREO A COR2. Due to the far northern latitude (~N85), there is a very wide range of possible longitudes. This is a very speculative longitude, and the CME could easily be farsided. |
