We report multisite observations devoted to the main-sequence δ Scuti star XX Pyx, conducted as 17th run of Delta Network. Over 125 nights a total 550 h usable time-series photometric B- and V-filter data were acquired involving both photoelectric CCD measurements at eight observatories spread around world, which represents most extensive single for any pulsating other than Sun obtained so far.
