AbstractWe present a description of the Prototype All-Sky Imager (PASI), a backend correlator and imager of the first station of the Long Wavelength Array (LWA1). PASI cross-correlates a live stream of 260 dual-polarization dipole antennas of the LWA1, creates all-sky images, and uploads them to the LWA-TV website in near real-time. PASI has recorded over 13,000 hours of all-sky images at frequencies between 10 and 88 MHz creating opportunities for new research and discoveries. We also report rate density and pulse energy density limits on transients at 38, 52, and 74 MHz, for pulse widths of 5 s. We limit transients at those frequencies with pulse energy densities of $>2.7 imes 10^{-23}$, $>1.1 imes 10^{-23}$, and $>2.8 imes 10^{-23}$ J m$^{-2}$ Hz$^{-1}$ to have rate densities $<1.2 imes10^{-4}$, $<5.6 imes10^{-4}$, and $<7.2 imes10^{-4}$ yr$^{-1}$ deg$^{-2}$
