Scientific paper

Within the 2 arcminute-radius position error circle of the recently discovered INTEGRAL source IGR J18027-1455 (ATEL #229), we have found two weak radio sources in the 1.4 GHz NVSS maps. The first one, NVSS J180239-145453, has an estimated J2000.0 ICRS position of RA=18h02m39.94s (+/-0.25s), DEC=-14d54'53.6" (+/-3.3") (1 sigma uncertainties), has a flux density of 6.9 mJy and has no IR counterpart in 2MASS (see Ks-band 2MASS plot, where position error ellipses represent 2 sigma uncertainties).
