CME Analysis Information (for CME activity ID: 2024-06-01T19:12:00-CME-001)
Catalog: M2M_CATALOG Data Level: 0 (0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis) Use as primary measurement: true Measurement Technique: SWPC_CAT Speed (km/s): 1503.0 Speed measured at height (Rs): None Entered Type: O Direction (LON/LAT in HEEQ): -168.0/ -6.0 Half Angular Width (degree): 45.0 Minor Half-width (degree): None Entered Tilt (degree): None Entered Time@21.5: 2024-06-01T21:09Z Info/Session URL: None Entered Note: Somewhat uncertain analysis of the outer, earlier front of this halo CME (possibly its shock), based on the fit with two coronagraphs. Only one coronagraph frame is available for STEREO A COR2 bc of a data gap, adding to the uncertainty of analysis. These parameters are somewhat confirmed by the location of a large backsided active region in helioseismology imagery from GONG which is likely the former AR 13679 that was at lat/lon -8/-170 at the time of event. No Notification has been sent for this activity yet. |
