Abstract
We analyze sensitive, high angular resolution (0."3) Very Large Array obser vations made at 6-cm of the thermal jet Cep A HW2 in two epochs separated b y 1.3 years. The subtraction of the maps made at the two epochs clearly sho ws the presence of brightness enhancements that travel in the jet at a velo city of 950 +/- 150 km s(-1). We also use these results to estimate an accu rate position for the exciting star of this jet.
