Caveats
This CME list is automatically generated. The detection algorithm is not perfect so there are sometimes false detections. Additionally, the signal to noise in the data varies with sky conditions which impacts the quality of detections. The observers will issue retractions for most false detections. We ask you to use caution when using the data for statistical purposes.
