                 NEW VARIABLE STARS



      During a survey of variable stars, on plates taken with the
Schmidt telescope 40/50/100 of Asiago Astrophysical Observatory. I
have found the following new variable stars:


  var        RA    1900   D      Max     min      type

GR 120     11h32m07s   +56d50'  16.7    17.4      RR
GR 121     11h34m15s   +54d37'  16.5    17.5      RR
GR 122     11h34m22s   +55d42'  16.7    17.5      RR
GR 123     11h52m47s   +55d48'  15.7    17.0      RR

GR 122 is near to a small galaxy.

          PHOTOELECTRIC OBSERVATIONS OF TX UMa

      Three photoelectric minima of TX UMa, obtained at the Nurnberg 
Observatory in the years 1965, 1966 and 1967 show large negative
O-C' s against the elements given by F. B. Wood (I) in GCVS and by
H. Rugemer (II) in SAC 38, respectively.

Min = JD 2416426. 783+3.0633175d . E+0.021d . sin (0.09474deg . E+64.42deg) (I)

Min = JD 2435584. 7500+3.0633175d. E    (II)

   Our photoelectric observations are inconsistent with the remark 
in SAC 38, page 105 "A minimum recently observed by K. Kordylewski 
is in agreement with our ephemeris".

     The Nurnberg observations of TX UMa lead to the new 
elements:

      Min = JD 2438856.353 + 3.063243d. E                (III)    

     The minima obtained at the Nurnberg Observatory are given
in the following Table together with the O-C' s computed with the 
formulas (I) to (III)
