*Note on countable unions of Corson countably compact spaces *

Comment.Math.Univ.Carolinae 45,3 (2004) 499-507. **Abstract:**We show that a compact space $K$ has a dense set of $G_\delta $ points if it can be covered by countably many Corson countably compact spaces. If these Corson countably compact spaces may be chosen to be dense in $K$, then $K$ is even Corson.

**Keywords:** Corson countably compact space, $G_\delta $ point, Corson compact space, Valdivia compact space

**AMS Subject Classification:** 54D30
