Seven giant radio pulses were recorded from the millisecond pulsar PSR B1937+21 during ~8.1min observation by the Ooty Radio Telescope (ORT) at 326.5MHz. Although sparse, these observations support most of the giant pulse behaviour reported at higher radio frequencies (430 to 2380MHz). Within the main component of the integrated profile, they are emitted only in a narrow (≲47µs) window of pulse phase, close to its peak. This has important implications for doing super-high precision timing of PSR B1937+21 at low radio frequencies.
