#### Abstract

Let $e_n$ be the connective cover of the Morava $E$-theory spectrum $E_n$ of height $n$. In this paper we compute its homology $H_\ast (e_n; \mathbb{F}_p)$ for any prime $p$ and $n \leqslant 4$ up to possible multiplicative extensions. In order to accomplish this we show that the Künneth spectral sequence based on an $\mathbb{E}_3$-algebra $R$ is multiplicative when the $R$-modules in question are commutative Salgebras. We then apply this result by working over $BP$ which is known to be an $\mathbb{E}_4$-algebra.
