We present the first combined study of the recently discovered source IGRJ16283-4838 with Swift, INTEGRAL, and RXTE. The source, discovered by INTEGRALon April 7, 2005, shows a highly absorbed (variable N_H = 0.4 - 1.7 x 1e231/cm**2) and flat (photon index = 1) spectrum in the Swift/XRT and RXTE/PCAdata. No optical counterpart is detectable (V > 20 mag), but a possibleinfrared counterpart within the Swift/XRT error radius is detected in the 2MASSand Spitzer/GLIMPSE survey. The observations suggest that IGR J16283-4838 is ahigh mass X-ray binary containing a neutron star embedded in Compton thickmaterial. This makes IGR J16283-4838 a member of the class of highly absorbedHMXBs, discovered by INTEGRAL.Comment: 8 pages, 3 figures, accepted for publication in Ap
