Abstract
Among the registered extremely high energy cosmic rays (EHECR, E > 1020 eV) there is a triplet of events in a circle with radius of 40 in the Galactic center region. With the use of the backtracking method for the calculation of EHECR trajectories in the Galactic magnetic it is shown that potential sources of galactic triplet can be microquasars SS433, GRS1915+105, magnetar SGR1900+14 and globular star cluster NGC6760.
