  We report the detection of periodic variations on the T_eff ~32 000 K DA
white dwarf star HE 1017-1352. We obtained time series photometry using the 4.1
m SOAR telescope on three separate nights for a total of 16.8 h. From the
frequency analysis we found four periods of 605 s, 556 s, 508 s and 869 s with
significant amplitudes above the 1/1000 false alarm probability detection
limit. The detected modes are compatible with low harmonic degree g-mode
non-radial pulsations with radial order higher than ~ 9. This detection
confirms the pulsation nature of HE 1017-1352 and thus the existence of the new
pulsating class of hot DA white dwarf stars. In addition, we detect a long
period of 1.52 h, compatible with a rotation period of DA white dwarf stars.
