Midcourse Space eXperiment (MSX) 8 μm image of the Cygnus X region overlaid with the peculiar motions for maser sources with parallax and proper motion measurements. The dotted line indicates the Galactic plane. The dots mark the water maser (NML Cyg, this paper) and the methanol maser sources (Rygl et al. 2012) and the center of Cyg OB2 (Kharchenko et al. 2005), with their distances labeled in kpc. The peculiar motions of sources are indicated with arrows. The approximate size of the Cyg OB2 association is denoted by a circle with diameter of 2° (Knödlseder 2000) (This figure is available in color in electronic form.)
