U, B, V, R_c, I_c Photometric Observations of the Dwarf Nova DX Andromedae During the Years 2018-2019

摘要

In this paper we present U, B,V, R_c, I_c 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,I_c 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.
