We report photometric observations of the optical transient Gaia17bqo which was discovered by Gaia on 2017-06-30 at magnitude G = 18.03. We confirmed Gaia17bqo with images taken on 2017-07-02 with the 0.6-m Zeiss telescope at the Terskol Observatory (see Fig. 1). There is no progenitor object on archival images. We detected a rapid decay of Gaia17bqo with changing its color within four days. The following magnitudes of the object were derived:
The magnitudes were calibrated against NOMAD field stars; they are not corrected for the Galactic foreground extinction.
