Result. are presented from a multisite photometric campaign on the pulsating subdwarf B star, PG 1047+003. Approximately 98h of data were obtained from three sites, with a duty cycle of ∼30 per cent. The light curve of PG 1047+003 is dominated by several frequencies in the range ∼6880-7500µHz (periods 133-145s). We identify, with some confidence, 18 frequencies between 5700 and 9605µHz (104-175s) down to an amplitude of 0.0004 in fractional intensity (0.04 per cent), thus doubling the number of published pulsation frequencies for this star. These pulsations correspond to low-order and low-degree acoustic modes. Several frequency spacings near 1.05µHz suggest a rotation period for the star of 11.0d.
