We analyzed high-cadence observations of a C5.7 flare on 1999 August 23 at Big Bear Solar Observatory (BBSO). The observing wavelength was 1.3 A in the blue wing of Hα, with a cadence of 0.033 s. In addition, the hard X-ray's time profile obtained by the Burst And Transient Source Experiment (BATSE) and BBSO high-resolution magnetograms was compared with our Hα observations to understand in detail the particle precipitation in this event. The important results are as follows:
