英文摘要	We simulate the evolution of supernova remnant (SNR) W51C. The simulation shows the existence of a new northeast edge. We present the magnetic field structure of the W51 complex (SNR W51C and two H II regions W51A/B) by employing the 11 cm survey data of Effelsberg. This new edge is identified and overlaps with W51A along the line of sight, which gives a new angular diameter of about 37' for the quasi-circular remnant. In addition, we assemble the OH spectral lines (1612/1665/1720 MHz) toward the complex by employing the newly released THOR (The HI OH Recombination line survey of Milky Way) data. We find that the known 1720 MHz OH maser in the W51B/C overlap area is located away from the detected 1612/1665 MHz absorption region. The latter is sitting at the peak of the H II region G49.2-0.35 within W51B.
