We have re-analyzed Einstein Observatory data on CTB 80 using phase folding method. Significant pulsation was found in both the HRI and IPC data with similar phase diagrams at periods near those predicted by the radio observations. An acceleration in PSR 1951+32 during the period October 1979-April 1980 is indicated. © 1994.
