Catalog: M2M_CATALOG
Data Level: 1 (0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis)
Use as primary measurement: true
Measurement Technique: None Entered
Detecting Instruments:
Image Type: direct
Speed (km/s): 357.0
Speed measured at height (Rs): None Entered
Type: S
Direction (LON/LAT in HEEQ): -13.0/ -1.0

Note: 
This measurement is using SOHO LASCO C2 in SWPC_CAT. The CME is faint in C2 and is not seen in either LASCO C3 or COR2A (Stereo imagery is available). The measurement is based off of the source location of the flare and associated eruption identified in SDO AIA imagery.
