摘要：
We report and discuss the steady brightening of eta Carinae, and conclude that this brightening is not an eruption, but an expected LBV S-Doradus phase which, typically, displays intense brightening coupled to strong reddening when the star moves redwards in the H-R diagram. The brightness gradient amounts to -0.(m) 15 y(-1) over the last two years.
