Using the recently determined spatial velocity components of the extreme runaway star HIP 60350 and a gravitation potential model of the Galaxy , we integrate the orbit of HIP 60350 back to the plane of the Galaxy .
In this way , a possible location of the formation of the star is determined .
We estimate the uncertainty of the result due to the uncertainties of the gravitational potential model and the errors in the spatial velocity components .
The place of birth lies ( within the errors ) near the position of the open cluster NGC 3603 .
However , the ejection event which occured about 20 Myr ago is in contradiction with the cluster mean age of 3 - 4 Myr .
We suggest that it occured at an earlier phase in sequential star formation in that region .
We discuss also ejection mechanisms .
Due to the rather high mass of the star ( about 5 { M _ { \odot } } ) , the most probable model is that of dynamical ejection .
