The radio-loud active galactic nucleus in M 87 hosts a powerful jet fueled bya super-massive black hole in its center. A bright feature 80 pc away from theM 87 core has been reported to show superluminal motions, and possibly to beconnected with a TeV flare observed around 2005. To complement these studiesand to understand the nature of this feature, we analyzed 2 cm VLBI data from15 observing runs between 2000 and 2009. This feature is successfully detectedat the milli-Jansky level from 2003 to 2007. Our detections show that itsmilli-arcsecond structure appears to be extended with a steep spectrum, and nocompact or rapidly moving features are observed. Our results do not favor ablazar scenario for this feature.
