[en] The 4m International Liquid Mirror Telescope (ILMT) is presently under commissioning phase at Devasthal Observatory (Nainital, India). This facility continuously scans the same strip (22' wide) of the sky (in g, r and i bands) with a fixed pointing towards the zenith direction. Consequently, it provides a unique opportunity for supernovae (SNe) detection and study. We estimated the SNe detection rate with the ILMT by considering the progenitor mass range for Type Ia SNe and core-collapse supernovae (CCSNe) as 3-8 MSun and 8-50 MSun, respectively. Here, the CCSNe mass range is for different types of events (Ibc, IIL, IIP, and IIn). Our calculation indicates that it is possible to detect hundreds of supernovae each year by implementing an optimal image subtraction technique. The photometric classification of SNe is also possible with the ILMT data. The observatory hosts two additional optical facilities (1.3m DFOT and 3.6m DOT) along with the ILMT and therefore, immediate monitoring of ILMT-detected transients/SNe is planned under the target of opportunity mode. The spectroscopy with DOT facility will be useful for the classification of SNe.
