In this paper we present U, B,V, Rc, Ic photometric observations of the dwarf nova DX Andromedae made in the years 2018–2019 at the private Rocchi observatory located in Spello (Umbria). We observed the variable for 86 nights in B, V, Rc, Ic photometric filters. We detected an outburst of this dwarf nova. We summarize the significant variations in the color indices during the outburst cycle and in the minimum phase.
