Abstract:
We present speckle observations of 48 double and multiple stars
observed with the 2-meter ``Telescope Bernard Lyot'' (TBL) in December
1995, January 1997 and June 1997. Angular separations, absolute
position angles and relative photometry result from these
observations. New orbital elements have been recalculated for 8
double stars.

Note (1): ν Cyg was in fact discovered as double and then not used as
reference star in the processing of BU 151
Note (2): For ε Hya, the angular separation ABxC was computed from AB,
AC and {DELTA}mAB as the distance between C and the photocenter of
AB.
Note (3): For orbits prior to 1982 (followed by a *), orbital elements were
found in the catalog of Worley & Heintz, 1983, Cat. V/39
