Distribution of the 6.7 GHz methanol maser spots in S255IR IRS3 taken before (circles) and after (triangles) the burst on MJD 55996 (JVLA-C; Hu et al. 2016) and MJD 57676 (JVLA-A; Moscadelli et al. 2017), respectively. The origin of the map coincides with the brightest spot at α(J2000) = 06^h 12^m53. s998, Δ(J2000)= 17°59′23.′′49. The relative position uncertainty of the spots between these two epochs is less than ~0.′′1. The symbol size is proportional to the maser brightness, and colors denote the radial velocity in km s⁻¹ according tothe right scale. The cross marks the position of the 5 GHz continuum emission (Moscadelli et al. 2017).
