AT2018cow was an energetic transient discovered on 16 June 2018 in the galaxy CGCG 137–068, at 60 Mpc. In this work, I will present observations of the object carried out with the Neil Gehrels Swift Observatory in X-rays and UV, during the first 27 days after detection. The good coverage in these bands revealed a very blue transient with an unusual, highly variable X-ray behavior. I will discuss the implications of these results.
