H. O. Vats, A. K. Singal, M. R. Deshpande, C. R. Shah, and S. Doshi, Physical Research Laboratory, Ahmedabad; and K. N. Iyer and R. Oza, Saurashtra University, Rajkot, report a marked increase in the intensity level of the average-pulse amplitude of PSR 0950+08 during the first half of August in 103-MHz observations made with the 5000-m**2 transit radio telescope at Rajkot. The average intensity, which peaked on Aug. 8, attained a level that was more than an order of magnitude higher than the normal average-pulse amplitude. At least 100 giant pulses were seen with an amplitude exceeding 100 times the average-pulse amplitude during a half-hour of transit time. Some of the strongest pulses reached a level of about 500 times the average-pulse amplitude.
