Astrometric VLBI observation of PSR 0329+54

We conducted VLBI experiments on the pulsar PSR 0329+54 with the Kashima (J apan)-Kalyazin (Russia) baseline in 1995 March and 1996 May. An absolute as trometric measurement was applied by using the analysis software SOLVE and CALC, which were developed by NASA/GSFC for geodesy and astrometry. Our mea surement results are consistent with the former results of a VLBI observati on by Bartel et al. (1985, AAA 39.041.005) and a VLA observation by Fomalon t et al. (1984, AAA 38.041.014) when proper motion (Harrison et al. 1993, A AA 57.126.049) is taken into account. By using our data set and Bartel et a l.'s data, the most precise proper motion and pulsar position in ICRF were obtained. The proper motion as mu(alpha): 17.3 +/- 0.8 mas yr(-1), mu(delta ) : - 11.5 +/- 0.6 mas yr(-1) and the coordinates at the epoch of 1995.0 ar e alpha : 03(h)32(m)59.(s)376 +/- 0.001, and delta : 54 degrees 34'43 " 504 +/- 0.007.
