The focus is on 4-neutrino mass and mixing models capable of explaining the LSND evidence of $\barν_μ\to \barν_e$ oscillations. The potential of the Fermilab neutrino detector MiniBooNE to observe supernova neutrinos is then addressed, and a general description of the detector is given. As of May, 2002, the MiniBooNE detector is fully operational.6 pages, 6 figures.
