IRAS 18460-0151 (OH 31.0 -0.2) -- a water fountain star.

The ATCA/VLA OH 1612 MHz maser survey to the northern sky found 286 OH-masing objects, 161 of them are new detections. Three water fountain stars were also observed: IRAS 18460-0151(img58), IRAS 18286-0959(img54) and IRAS 18450-0148(img57). (from Sevenster et al., 2001A&A...366..481S)

IR counterparts of all 23 masing source and 18 very red objects are identified in Spitzer/GLIMPSE images at 3.6, 4.5, 5.8, and 8.0 μm. Two new water fountain stars (IRAS 18286-0959, IRAS 18460-0151) and an SiO maser with companion nebulosity (IRAS 19027+0517) are found by Nobeyama 45m observations. The non-detection of HCO+, J=1-0 for the H2O maser sources demonstrates that they are not young stellar objects. The H2O masers of IRAS 18460 covering -60 ~ 225 km/s and so,Vexp = ~142 km/s, Vlsr = ~82 km/s.(from Deguchi et al., 2007ApJ...664.1130D)
