Lightcurves of seven main belt asteroids: 289 Nenetta, 698 Ernestina, 901 Brunsia, 1394 Algoa, 3657 Ermolova, 5240 Kwasan and 5448 Siebold are presented. The photometric observations were carried out in 2017 with two of the telescopes of the Bulgarian National Astronomical Observatory Rozhen: 50/70 Schmidt telescope and 2m Ritchey-Chrétien-Coude telescope. These asteroids are part of our long-term photometry program, targeted on studying the shape and spin of the minor planets in the Solar System.
