  We present the analysis of 65 hours of high speed photometric observations of
HD 12098 taken from State Observatory, Naini Tal and Gurushikhar Observatory,
Mt.Abu on sixteen nights spanning from November 1999 to November 2000. HD 12098
is the first rapidly oscillating Ap star discovered from the `Naini Tal-Cape
survey for northern hemisphere roAp stars'. It is the 32nd in the complete
list. HD 12098 exhibits one predominant mode of oscillation at nu_1 = 2.1738
mHz. The second-most significant frequency in our data is at nu_2 = 2.1641 mHz
with a 1 cycle/day alias ambiguity. We argue that nu_2 is a rotational sidelobe
of nu_1, rather than an independent pulsation mode. Evidence for the presence
of two other frequencies at 2.1807 and 2.3056 mHz is also presented.
