           S 10804 Boo - RR LYRAE STAR NOW CONFIRMED


  The variability of the star S 10804 Boo (14h03.6m, +24deg48', 1950.0) was
discovered by Gessner (1978). She suspected that the object was an RR Lyrae
star of subtype c.
  The star was observed photoelectrically in 9 nights during the years
1984 (4 nights) and 1985 (5 nights) with the Sonneberg 60 cm telescope II.
Altogether 333 single measurements in the V region could be discussed. The
light curve computed with the elements

                               [FIGURE 1]




now clearly shows that the object is an RR Lyrae star of subtype ab with an
amplitude of about 1.0 mag in V.
