This article describes in detail a burst from PSR 0950+08 on July 29,
1992. This event was observed by two radio telescopes (separated by si
milar to 200 km) operating at 103 MHz. There exists a very convincing
indirect evidence that at the same time the pulsar also emitted large
X-ray flux. The X-ray flux during the event compares with that during
a solar X-ray flare. During the event the Sun was extraordinarily quie
t as the solar X-ray flux < 3 x 10(-7) W/m(2) only was observed. The c
ause for the burst is quite unknown and may be complex. However, a pos
sibility of accretion of a comet-like object by pulsar may provide rea
sonable explanation of the observations. These results open some inter
esting questions about the pulsar physics.
