ABSTRACT
The non-radially pulsating subdwarf B star PG 0014+067 has previously been presented as
a classic case for asteroseismological study, having a moderately rich mode spectrum un-
complicated by severe rotational splitting. Notwithstanding the excellence of previous work,
empirical evidence for mode identification is needed to test the modelling results. Conse-
quently high-speed multicolour photometry was obtained over six nights in 2004 August using
