        LIGHT VARIATIONS OF THE Be STAR HD 63462


    Classified B0Vpe? in the Bright Star Catalogue and B1IV?nne
by Hiltner et al. (1969) this star has been little observed so
far. Merrill and Burwell (1943) note Halpha in emission in December
1934, the profile being somewhat unsymmetrical. Jaschek et al.
(1969) characterize the spectrum in March 7966 as almost 
continuous with strong central emission in Hbeta and all other Balmer
lines practically flat. Henize (1976) finds moderately sharp and
rather weak emission in Halpha. Photometry by Feinstein (1968) 
suggests marginal photometric variations, Buscombe & Kennedy (1965)
report radial velocity variations.
    UBV observations of HD 63462 relative to HD 60863 were 
obtained on 15 nights between January 16 and January 31, 1977 
using the Bochum University 61cm telescope at La Silla, Chile.
Reduction procedures were the same as those described by Stift
(1978). Combining all observations made within an interval of
less than 1 hour leads to an internal precision of ~0.003m. A
plot of the observations versus Julian Date is shown in Fig. 1.
Variations on a time scale of a few days attain 0.02m in V, colour
variations are marginal. No periodicity can be found; HD 63462
shows irregular or semiregular behaviour similar to that of the
other Be stars where light curves are available (e.g. HD 88661,
HD 174237, HD 187399).
