The satellite photometry of the _ Scuti star 0² Tau obtained with the Wide- Field Infrared Explorer (WIRE) led to the detection of 12 frequencies of pulsation (Poretti et al. 2002). We examine the available ground-based photometry in the literature to check whether these frequencies are also present. The re-analysis of the 1986 Delta Scuti Network data leads to 10 statistically significant frequencies (amplitude signal/noise ratio greater than 4.0). 9 of these 10 frequencies are in excellent agreement with those detected from space, while the 10th frequency is seen as a peak in the WIRE residuals, though not at a statistically significant level. Previous reports on amplitude variability are confirmed.
