chromatic localization

The Bousfield localization of spectra $L_{E(n)}$ at $n$th Morava E-theory is called *chromatic localization*. The tower of chromatic localizations as $n$ ranges is called the *chromatic tower*, leading to the *chromatic filtration*. This is the subject of chromatic homotopy theory.

Chromatic localization on complex oriented cohomology theories is like the restriction to the closed substack

$\mathcal{M}_{FG}^{\leq n+1}
\hookrightarrow
\mathcal{M}_{FG} \times Spec \mathbb{Z}_{(p)}$

of the moduli stack of formal groups on those of height $\geq n+1$.

(e.g. Lurie, lect 22, above theorem 1)

In this way the localization tower at the Morava E-theories exhibits the chromatic filtration in chromatic homotopy theory.
