摘要：
We present the Hα flux measurements for 44 nearby dwarf galaxies, derived from the observations at the 6-m BTA telescope. Hα fluxes were used to determine the rate of integral star formation of galaxies, SFR. For the observed galaxies the value of log SFR lies in the range from 0 to −8 [M⊙/yr]. The specific star formation rate for all the sample galaxies does not exceed the limit of log SSFR = −9.2 [yr−1]. A burst of star formation was detected in the center of a nearby dwarf galaxy UGC2172.
