Abstract We report on the properties of strong pulses from PSR B0656+14 by analyzing the data obtained using the Urumqi 25-m radio telescope at 1540 MHz from August 2007 to September 2010. In 44 h of observational data, a total of 67 pulses with signal-to-noise ratios above a 5σ threshold were detected. The peak flux densities of these pulses are 58 to 194 times that of the average profile, and their pulse energies are 3 to 68 times that of the average pulse. These pulses are clustered around phases about 5° ahead of the peak of the average profile. Compared with the width of the average profile, they are relatively narrow, with the full widths at half-maximum ranging from 0.28° to 1.78° . The distribution of pulse-energies follows a lognormal distribution. These sporadic strong pulses detected from PSR B0656+14 have different characteristics from both typical giant pulses and its regular pulses
