Results of photoelectric observations of HDE 245770 spreaded over six years are presented. No variations greater than some hundreths of magnitudes are evident in contrast with the ancient light history, which is more complex. A sensible variation of the colour indices is present on a time scale of tens of years. The temporal analysis of these data shows some evidence of orbital periodicity.
