During the past decade Eta Car has brightened markedly, possibly indicating achange of state. Here we summarize photometry gathered by the Hubble SpaceTelescope as part of the HST Treasury Project on this object. Our data includeSTIS/CCD acquisition images, ACS/HRC images in four filters, and syntheticphotometry in flux-calibrated STIS spectra. The HST's spatial resolution allowsus to examine the central star separate from the bright circumstellar ejecta.Its apparent brightness continued to increase briskly during 2002--06,especially after the mid-2003 spectroscopic event. If this trend continues, thecentral star will soon become brighter than its ejecta, quite different fromthe state that existed only a few years ago. One precedent may be the rapidchange observed in 1938--1953. We conjecture that the star's mass-loss rate hasbeen decreasing throughout the past century.Comment: Accepted for publication in AJ. 31 pages including: 6 Figures and 5  Table
