A C-type CME was detected by STEREO-A COR2 at 5:39 UT on 11/10/2012. The estimated speed is ~900 km/s. Based on preliminary heliospheric modeling carried out at NASA GSFC Space Weather Research Center, it is estimated that the CME may impact Messenger on 11/11/2012 at 01:07 UT. Earth may experience ย a possible glancing blow from the CME on 11/13/2012 around 12 UT. The estimated times have errors of +-7 hours.
