Abstract. The results of the CCD photometry of the 1995 FG Virginis multi-site campaign, orga-
nized by the Delta Scuti Network, are presented. Between March 16 and April 20, 1995 over 120
hours of CCD measurements were obtained. The ten frequencies of FG Vir, known from the previous
campaign (1993), range from 9.20 to 34.12 cycles/day (106.5 and 394.9 µHz). Three new frequencies
at 16.07, 19.23 and 24.19 c/d (186.0, 222.5 and 279.9 µHz) were detected. The precision of the FG
Vir measurements was better than 3.5 mmag per single 1-min integration. It is shown that the present
CCD measurements are of similar quality as those obtained simultaneously by photometers with
