The Luminosity Oscillations Imager is a part of the VIRGO instrument to be flown aboard the Solar and Heliospheric Observatory in mid 1995. Using a ground-based version of the instrument, we have detected low-l modes with a time series spanning 163 days. The low resolution capability of the instrument allows the identification of individual tesseral orders for l=2 to 5. The data reduction method prevents from observing the l=0 modes, and reduces the amplitude of the l=1 modes with m=+/-1. The frequencies and, for the first time, the linear component of the mode splitting (a_1_) are given for l=2 to 5 for each order n. The frequencies and the a_1_ are obtained by fitting simultaneously the 2l+1 spectra using maximum likelihood estimators. The splittings are compared with other published values.
