During first months of the SRG operation the ART-XC telescope (working energy range 4-30 keV) performed observations in different modes: scanning observations of a number of sky fields, pointing observations and all-sky survey. These observations allowed us to discover new transient sources with different observational properties. In particular, the typical time variability of new sources is spanned from dozens seconds or several hours (e.g., for SRGt J123822.3-253206) up to several days (e.g., for SRGa J174956-34086). Spectral characteristics of new sources are also significantly different, that point out to their different nature. In addition to new sources a number of known transient ones in our and nearby galaxies were studied as well. In this presentation we report above mentioned results as well as briefly present the system for the quick look analysis of the ART-XC data.
