The location of the subdwarf star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For 2M 1938+46, the location is 19h 38m 33.00 and 46° 03` 59.00 .
2M 1938+46 has a spectral type of sdB+M.
