      PRELIMINARY ELEMENTS FOR BV 1621 CMa = HD 56429



   Markworth (IBVS No. 921) found this variable and published
two minima. Popper and Andersen (IBVS No. 1298) obtained 
spectrograms which shows that the star is a spectroscopic binary
with a period of approximately 4.80d.  From their uvby  
photometry they found the period close to 4.801d, a deep secondary
minimum and a duration of the minima of 0.35d.
   A new investigation of all available Bamberg-Sky-Survey
plates shows the following minima:

671.5       42038.048       -0.131   8.7

With this minima preliminary elements are established:
        Min.= 2438814.273d + 4.801052d E.
In maximum-light, the star is constant at magnitude 8.1m pg,
it belongs to the Algol-class.

    ELEMENTS FOR BV 840 Cen, BV 1172 Cen, BV 1444 Ara,
               V 449 Cen AND V 603 Cen



        On plates of the Bamberg-Sky-Survey these five long-period
variables were investigated using the Argelander-step method.      
The magnitudes of the comparison stars were determined with
SA 153 and SA 177(1). Using all maxima of Table 2, together
with values of some ascending and descending branches, the 
elements of Table 1 were determined.
