Following the discovery of a new X-ray source IGRJ05414-6858 with the INTEGRAL observatory (ATel #2695) the Swift target of opportunity observations were performed on June 25 with a total exposure of ~4 ksec. Only one relatively faint X-ray source was clearly detected at the position of RA=05h41m26.7s, Dec=-69g01m25s (J2000, an uncertainty of ~3"), that is about of 3' away from the position of IGRJ05414-6858, reported in ATel #2695. The source spectrum in the 0.6-10 keV energy band can be fit with a simple power law model with a photon index 0.33+/-0.12 and flux of 8.1(+0.9/-1.7)x10^-12 erg/cm/s, that is generally consistent with the INTEGRAL one.

A possible infrared counterpart 2MASS 05412663-6901224 with magnitudes J=15.084, H=14.853, K=14.989 was found inside of the SWIFT error circle. This star is also clearly seen in the USNO-B1 image with the name of 0209-0129816 and magnitude of R=15.6.

We thank the Swift team for their rapid scheduling of these observations.
