            IMPROVED LIGHT ELEMENTS OF HX ARAE

HX Ara was identified as a RRc variable in 1975 (Duerbeck and Walter,
Astr. Astrophys. 49, 471 (1976). A new light maximum is derived from
observations in B and V made by one of us (K.W.) with the 50 cm telescope 
of the European Southern Observatory in 1976:

   J.D.hel. = 2443005.5745 +- 0.0020.

The following improved light elements are derived:

   J.D.hel.(max.) = 2442638.5138 + 0.219403 E.
