Observations of Markarian 231 at 1.1 microns taken with NICMOS on the HubbleSpace Telescope are described. The brightness of the object in the nearinfrared and the inherent short-term stability of the NICMOS optical andinstrumental system enables application of special observational and analysistechniques that effectively increase high spatial resolution. By these means,we set an upper limit on the size of the core of the AGN nucleus at 8 mascorresponding to a radial projected distance from the center of MArkarian 231of ~ 3pc.Comment: 13 pages + 4 figures, accepted to PAS
