Abstract:	The current status of experiments with SND detector at VEPP-2M $e^+e^-$ collider in the energy range $2E_0=0.4-1.4$ GeV is given. The new results of analysis of $phi$ decay into $pi^0pi^0gamma$, $etapi^0gamma$ are based on the full SND statistics corresponding 20 million of $phi$ decay. New measurement of $omega opi^0pi^0gamma$ decay and a first observation of $ ho opi^0pi^0gamma$ are presented. The accuracy of many other rare decays of light vector mesons was improved. In the energy range $2E_0=1.0div1.4$ GeV the cross sections of the processes $e^+e^- oomegapi^0$ and $e^+e^- opi^+pi^-pi^0$ were measured. The results of the fitting of data are discussed.
