Spectral observations of transient objects (Gaia20blb, Gaia20cxk, Gaia20cek, Gaia20bpl, Gaia20bor) discovered within the Gaia Science Alerts program were carried out in the 2-meter telescope of the Shamakhi Astrophysics Observatory named after N.Tusi of ANAS (N.Ismayilov, H.Mik Khalilov, I. Alakbarov, S. Alishov, S. Bagirli).

We report on the spectroscopic observations of five transient events detected by the Gaia Science Alerts programme (http://gsaweb.ast.cam.ac.uk/alerts). Spectra were taken with 2-m Shamakhy Astrophysical Observatory (ShAO) telescope in Azerbaijan. Observations were made at the Cassegrain focus of the 2-m telescope with UAGS + objective Canon EF (f=200 mm, f/2) + CCD Andor (ikonL-936-BEX2-DD 2048x2048, px=13.5 um) spectrograph. The spectral range is 3750-7650 A. The width of the slit was 3.3 arcsec. The spectral resolution is about 6 A/px. Spectrophotometric standard stars were observed every night immediately after the object. The links provided as IAU names of the events lead to the Transient Name Server pages with detailed information and spectra.
