1.6-GHz EVN radio continuum maps of the nuclear region of the NLS1 NGC 4051 (Giroletti & Panessa 2009). The size of the beam is 13.5 × 11.3 mas. The cross indicates the position (RA
; Dec
) of the maser derived with the VLA A-array (Hagiwara 2007; present work). The circle represents the 0
1 arcsec VLA nominal position accuracy of the maser emission.
