The Plane of our Galaxy is regularly observed by the INTEGRAL satellite bymeans of scheduled scans. We present here results from the IBIS/ISGRIinstrument using data from the first two Galactic Plane Scans performed at theend of the Performance Verification phase, while INTEGRAL was pointed towardsthe Cygnus region.  Considering the predicted IBIS sensitivity, we expected three persistentsources to be detectable: Cyg X--1, Cyg X--3, Cyg X--2, in order of decreasingintensity in the hard-X energy range (>15 keV). In addition to these sources,our analysis revealed two more transient sources, confirming the unprecedentedIBIS sensitivity. For each exposure (~2200 s) of the two scans, we report ondetected source fluxes, variabilities and localisation accuracies.Comment: 4 pages, 4 figures (3 in color), accepted for pub. in A&A, INTEGRAl  special issu
