We report on 2-MASS archival data analyses of the field of IGR J16283-4838 (Atel #456, 458, 459). A clear source is detected in the 2-MASS All-Sky Quicklook image archive (with name 2MASS J16281083-4838560) in the K band at a position consistent with the X-ray position obtained with the SWIFT-XRT detector (Atel #459), while only lower limits are obtained in the J and H bands.
The position of the source is R.A. = 16h 28m 10.83s, Decl. =-48deg 38' 56.1" (equinox 2000.0; nominal uncertainty about 0".11) which is about 1.7" from the best position returned from SWIFT-XRT.
Magnitude estimates are Ks
= 13.95 +- 0.058,J > 16.8 , H > 15.8 (95% lower limits).
The source is not detected in DSS-2 plates in either the red or the infra-red image.
The combined 2-MASS J H K image can be found at http://isdcul3.unige.ch/~rodrigue/images/IGRJ16283_Infrared.jpg
More observations are encouraged to confirm or infirm the association of this possible counterpart with the X-ray source as long as the latter still shows X-ray activity.
