We present a description of the Prototype All-Sky Imager (PASI), backend correlator and imager first station Long Wavelength Array (LWA1). PASI cross-correlates live stream 260 dual-polarization dipole antennas LWA1, creates all-sky images, uploads them to LWA-TV website in near real time. has recorded over 13,000[Formula: see text]hr images at frequencies between 10 88[Formula: text]MHz creating opportunities for new research discoveries. also report rate density pulse energy limits on transients 38, 52, 74[Formula: text]MHz, widths 5[Formula: text]s. limit those with densities [Formula: text][Formula: text], text]J[Formula: text]m[Formula: text]Hz[Formula: text] have year[Formula: text].
