\IBVSTrem{
The variability of GSC 0867.0545 has been found as part of a programme
to discover and classify new variables using CCD observations of
selected fields on the edge of the northern Milky Way (eg.\ Bernhard \&
Lloyd 2000). Additional observations were performed on 5 nights
between January and February 2001 (W. Moschner, P. Frank) and 7 nights
between March and May 2001 (K. Bernhard). This star has previously been
referred to as Brh V44 (Bernhard 2000, 2001, Moschner 2001).
The ephemeris was calculated using the ``Phase Dispersion
Minimization'' method:
