            V 348 Sgr BROUGHT UP TO DATE

     The peculiar irregular variable V 348 Sgr (Ref. 1)
centered at 18h24m, -23deg, was examined by Mrs. Jean Hales
Anderson (Ref. 2), at the Harvard Observatory on over

  Fig. 1: Estimates of V 348 Sgr from 1957 to 1969. Each strip
  represents an interval of 2000 days the first starting with
  JD 2435000, the last ending with 2441000. Abscissa markers
  indicate intervals of 600 days and the ordinate markers
  photographic magnitudes 13.0 and 15.0. Small symbols 1-4 
  observations; intermediate 5-9; and large 10-16.


600 patrol plates between JD 2410000 and 35000. It has now
been examined on over 450 Nantucket plates taken with the
Maria Mitchell 7 1/2 Cooke Triplet Telescope giving a scale of
248" per mm. Figure 1 for JD 2435000 to 40500 brings the
observations up to the present date. These magnitude estimates
confirm earlier observations that the star V 348 Sgr is
irregular.
      I am deeply indebted to the U. S. National Science
Foundation for the grant to the Maria Mitchell Observatory
that made this investigation possible.
