Z. Abraham and T. P. Dominici, Sao Paulo University and Sao Paulo State Research Foundation, report that radio measurements at 7 mm, made at the Itapetinga Radio Observatory, show that the flux density decreased from 3 Jy on May 22 to 1.5 Jy on June 20, remaining constant since then. A. Damineli, N. Leister, and R. Levenhagen report that spectroscopy, obtained at the Pico dos Dias Observatory, shows the complete disappearance of the [Ne III] 386.8-nm spectral line on June 23. Both results indicate that eta Car has entered the deepest phase of the 2003.5 event, as predicted by Damineli et al. (2000, Ap.J. 528, L101).
