Query: Supernova forecast with strong lensing   In the coming LSST era, we will observe $\mathcal{O}(100)$ of lensed
supernovae (SNe). In this paper, we investigate possibility for predicting time
and sky position of a supernova using strong lensing. We find that it will be
possible to predict the time and position of the fourth image of SNe which
produce four images by strong lensing, with combined information from the three
previous images. It is useful to perform multi-messenger observations of the
very early phase of supernova explosions including the shock breakout.
