We report the detection and observed characteristics of giant pulses from theCrab Nebula pulsar (B0531+21) in four frequency bands covering 20-84 MHz usingthe recently-completed Long Wavelength Array Station 1 (LWA1) radio telescope.In 10 hours of observations distributed over a 72-day period in Fall of 2012,33 giant pulses having peak flux densities between 400 Jy and 2000 Jy weredetected. Twenty-two of these pulses were detected simultaneously in channelsof 16 MHz bandwidth centered at 44 MHz, 60 MHz, and 76 MHz, including one pulsewhich was also detected in a channel centered at 28 MHz. We quantify statisticsof pulse amplitude and pulse shape characteristics, including pulse broadening.Amplitude statistics are consistent with expectations based on extrapolationsfrom previous work at higher and lower frequencies. Pulse broadening is foundto be relatively high, but not significantly greater than expected. We presentprocedures that have been found to be effective for observing giant pulses inthis frequency range.
