Scientific paper

We present the images of Mrk 231 using VSOP and VLBA archival data. Mrk 231 is one of the nearby objects with a developed radio lobe at parsec-scales, and is categorized as a Compact Symmetric Object (CSO). These images allows us to estimate the age of last Mrk 231 outburst using three different methods: kinematic aging, the synchrotron aging and an adiabatic cooling model aging. With kinematic aging, we derived upper limit of the proper motion of 0.47 c, which gives the lower limit for the age of 170 yrs.
