     Further to identifications for TmzV66, note that the star identified is
a carbon star (CGCS 634), verified by Stephenson in the second carbon-star
catalogue.  The spectral type (M4) is in error in the Dearborn catalogue.
However, nearby is BD+52 790 = NSV 1519, which was also observed in the
Dearborn survey at type M4, evidently confirmed by Stephenson (see notes in
the CGCS catalogue).  Thus:


DO 28090 = CGCS 634 = C* 3241 = IRAS 04113+5248 = GSC 3719-0598 = TmzV66, etc.
         as per Kato-san's message.  Note that the interpretation of the IRAS
         spectrum as "oxygen-rich" must be in error.  

BD+52 790 = NSV 1519 = IRAS 04114+5252 = DO 28094 (M4) = GSC 3719-0166:
          4 15 20.74  +52 59 44.8 (2000, ACT); V = 9.33, B-V = 1.97 (Neckel 
          1974A&AS...18..169N).  Tycho:  V = 9.32 +/-0.03, B-V = 1.96 +/-0.14.

Finally, Stephenson suggests that IRC +50112, which lies midway between the
two similarly-bright red stars, probably is a blend of the two stars because
of the low angular resolution of the IRC survey.
