This is an updated measurement that uses a negative latitude more consistent with the location of the CME's source signature from AR2790. SOHO LASCO data was still unavailable when this measurement was made. |

This is a preliminary measurement made with SWPC_CAT using only STEREO A COR2 difference imagery since SOHO LASCO data is unavailable during real-time analysis. The chosen longitude is based on the corresponding eruption signature visible in SDO AIA 193/304. |
