Orbits of the July Pegasid meteors observed during 2008 to 2011

During 2008 to 2011, we observed 63 TV meteors of the July Pegasids simultaneously with the SonotaCo Network in Japan. The activity period of the stream was determined as July 6-19. We derived the corrected radiant alpha_G = 349.6 deg, delta_G = +11.3 deg at the solar longitude = 110.9 deg (equinox 2000.0), and geocentric velocity V_G = 63.9 km/s. In addition, the theoretical radiant and geocentric velocity from Comet Bradfield (1979 X = C/1979 Y1) are in accordance with these values, as Rendtel et al. (1995) and Jenniskens (2006) already suggested. From this fact, we are able to confirm that Comet Bradfield (1979 X) is the parent comet of the July Pegasids.
