  Seven giant radio pulses were recorded from the millisecond pulsar PSR
B1937+21 during $\approx$ 8.1 minutes observation by the Ooty Radio Telescope
(ORT) at 326.5 MHz. Although sparse, these observations support most of the
giant pulse behavior reported at higher radio frequencies (430 to 2380 MHz).
Within the main componentof the integrated profile, they are emitted only in a
narrow ($\la$ 47 $\mu$s) 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.
